Yes, state legislators should be held criminally liable for offensive speech. State legislators have the responsibility of creating laws. As a lawmaker one has the ability to discriminate based on race, ethnicity, and gender. No state legislator should spew offensive speech without being held criminally liable for their words. It's far too risky.
Legislators who discriminate against women, minorities or anyone should be held accountable and punished. It is not acceptable in this country to discriminate in any way, shape or form. No matter who the so-called president is and what their personal views are, discrimination is illegal and must be punished no matter what.
Ultimately, if a person wants to say offensive things, they have a right to say offensive things. There's no right to stop someone from being mean. There's also no law that stops people from saying things that other people think are incorrect. State legislators have to be able to say what they want to say.
Legislators should not be held liable for offensive speech against women and minorities. In the United States, we have and should be guranteed freedom of speech. Critical speech is included in this category, as well as creative expression of this speech. There is a line between inflammatory and freedom of speech. The latter should be protected.
