Some left-handers want to write normally because they're used to it. Other left-handers feel like it's more natural to mirror write and and feel discriminated against for not being allowed by their teacher to mirror write their homework. http://how-to-speed-up-research.wikia.com...
I accept to argue that mirror-writing should not be accepted by society. Either way you tackle the issue, one party will have to adjust their lifestyle. Either left-handed people will have to adapt to the currently accepted format of writing, or the rest of the population will have to adjust to reading mirror-writing. The biggest support for not accepting it is the matter of pleasing the majority. Only 15% of the population is left-handed , so they are the minority party in this scenario. Forcing the acceptance of mirror-writing would cause a burden on the majority population, and a rather unnecessary one at that.
Mirror-writing also causes variation in writing format. The reason that formatting exists is so there is a common structure in writing. A majority of the population would continue to use the accepted format, while a fraction would use mirror-writing. This would cause confusion among those who cannot read mirror-writing and miscommunication through communicating parties. The matter of mirror-writing can easily be overcome by left-handed people by natural conditioning.
Assuming my opponent is referring to college professors, this institution is optional. A student chooses to attend a college and which courses to attend. The professor is expected to use the teaching and classroom structure that best helps their teaching. The majority of colleges follow MLA formatting and citation, which is never natural to even right-handed writers at first. Formatting your paper in MLA style will eventually become habitual and natural through repetition. Also, physical writing in a classroom setting is becoming rare in the technology-driven society. Typing is not dominated by left-hand or right hand, but rather uses both hands to effectively and efficiently convey the writing in a legible form. It would be useless to shift society to accept hand-written mirror-writing when writing in itself is dying.
It's really easy for anyone to train themself to be good at mirror reading. Just because most people can't already mirror read doesn't mean it's not the case that almost everybody would quickly gain the skill to mirror read after a very short bit of training. On the other hand, some people have a disorder of mirror writing without realizing it some of the time they write and can't be trained to tell in all situations whether or not they're mirror writing and it would be really bad for those people to be unable to get a restaurant prep job just because that job includes about 8 seconds a day of dating a lid with masking tape because that would be discriminating against disabilities. Not all left-handers want to mirror write but those who want to should be allowed to because otherwise, they will endlessly suffer from pressing against binder rings and smudging pencil lead. Maybe there's no need to make a law for all teachers and jobs to accept mirror writing but there's no rule that individual bosses who want to accept mirror writing can't and that individual teachers can't provide a second stack of handouts and tests that are mirror printed for those students who want to mirror write to take a copy from. Some of those bosses who chose to accept mirror writing might want to quickly get their struggle to mirror read done and gone by buying mirror printed books from now on, and to enable them to do so, there should be a book publishing company that produces a few inverted versions of each book it produces, all of which should be available to buy online at http://www.chapters.indigo.ca..., and for each book, more inverted copies of it should get produced when it's about to run out and not after it already has so that anyone who wants to buy an inverted copy of a specific book online will always be able to. Left-handers who never started mirror writing want wish they were allowed to and then get a job that allows them to, once they start mirror writing would quickly get good at mirror writing with practice, and after more time of mirror writing would get really good at reading their own mirror writing, but could also further accelerate the ability to read their own mirror writing by buying inverted copies of books. Although, it's not necessary to make a law to accept mirror writing, there certainly shouldn't be a law that a boss is not allowed to accept mirror writing, and maybe over time, more bosses will copy other bosses by accepting mirror writing.
