Usually these people tend to hate tomboys who prefer guy friends, assuming they're gay, lesbian womanizers who have no control and love girlies a lot. They hate autistic people as well. As indicated by my picture, the Boy Scouts espouced these kinda beliefs. Worse than Hitler if you ask me. Puritanism is one of the worst forms of beliefs alive today. It's annoying that these arrogant types are allowed to breathe air.
Orthodox people are so firm in their belief that they fail to see the truth, they fail to believe what is really in front of their eyes. They are so arrogant that they totally have no mercy for others, that firm they are with their belief that they even discriminate other people i.E., people of other religion or other beliefs,thus they end up being cruel.
I kind of replaced orthodox with fundamentalist because it makes more sense to me, and YES, I believe people with orthodox beliefs are a lot more cruel and arrogant because they have mastered the art of lying to themselves and believing in those lies. Orthodox believers are also the most closed-minded of all because they have their belief and close the door upon any opposing belief without looking at it in a logical way. They say we can be dogmatic, we know all there is to know, so they don't question anything or look at things in a logical way because being dogmatic and orthodox tells them they cannot question. People who believe like this are the most arrogant people of all because they don't see shades of grey, only black and white/right and wrong, and they are very resistant to any kind of change.
The big issue is that we don't agree with the majority of people on this. Tolerance goes for anyone but the intolerant. At least that's the way most people act. Disliking homosexual activity is not the same as being a Nazi or a member of the Ku Klux Klan, as much as we are demonized in this way,
Dictionary.Com gives five definitions of the term "orthodox." In my opinion, none of these necessarily refer cruel or arrogant beliefs:
1.Of, pertaining to, or conforming to the approved form of any doctrine, philosophy, ideology, etc.
This definition includes any doctoring that is approved by any group. While some will of course be cruel or arrogant such as the Nazi Party platform, many such as the basic beliefs of most major modern religions have lead to great humanitarian advances in our global society. This term would also apply to people who conform to things like the constitution, the Red Cross mission statement, or the theory of relativity. This definition is simply too broad to generalize as cruel or arrogant.
2.Of, pertaining to, or conforming to beliefs, attitudes, or modes of conduct that are generally approved.
In order for a belief to be "orthodox by this definition, it simply has to be generally accepted. Most normal people are not ok with extreme cruelty or arrogance.
3.Customary or conventional, as a means or method; established.
Once again, common place or established can refer to cruel or arrogant practices, but in modern, civilized parts of the world, this is simply not the case.
4.Sound or correct in opinion or doctrine, especially theological or religious doctrine.
Someone who is being cruel or arrogant is typically incorrect and therefore not orthodox.
5.Conforming to the Christian faith as represented in the creeds of the early church.
This one is most likely what the author of the question was thinking of. But if one actually reads the creeds of the early church such as the Apostles and Nicene Creed, they will read statements that are full of nothing more than innocent declarations of trinitarian beliefs that are in no way cruel or arrogant.
I think that the debate that would stem from this question would be much better if the question's author had attacked a specific institution such as the Boy Scouts and their practices instead of clumping virtually everyone together under the vague umbrella of "orthodox" and then referring to us all as cruel and arrogant.
