It appears to me that we are excluding voices from public discourse because, in the opinion of a powerful group, they have been rude.
One person's rude criticism can easily become another person's hate speech.
People get sick die because of political decisions, and people gain great amounts of wealth because of political decisions.
People maintain comfortable places in society or remain in fully employed poverty because of political decisions.
There is very little in peoples' lives that aren't affected by politics.
If you're in a position for politics to not affect you because it's just an abstract topic of conversation, you're part of a privileged class of people who aren't being scrutinized and blamed because of your inherent, born qualities. Congratulations.
I am more tolerant and wise than you because I can separate political thought and speech from political action. You, apparently, cannot. I am being charitable by calling you a control freak who cannot handle having their deeply cherished opinions challenged.
