When a person accuses someone else of hatred and wanting to murder people simply for using pejoratives, yes. I think that’s an attempt to quiet the opposition.
I’m not a hater simply because I call a homosexual a homo (short for homosexual) or a sodomite. The use of a pejorative may be impolite, but it doesn’t make one a hater or a murderer.
Liberals like to polarize speech to shut down opposition. Make a single negative point about blacks, such as their high illegitimacy rate, and we’re called racists. Likewise, calling people haters and murderers simply because they use a pejorative is also polarizing.
Finally, you confuse politeness with cowardice.
I don't think anyone here said that.
