From a recent question on Quora, regarding engagement with intolerant conservatives...
My typical tact is NOT to "communicate" with them. Ignore them. Leave them be. You're wasting your breath. (Or, at least that's how I feel.)
Let narrow minded fools remain that way until they're ready to pay attention, and still don't allow one's self to be goaded into an argument with such fools under false pretenses.
Some people only look for evidence to support their already established conclusions and will talk you and themselves in useless circles (usually a tact absorbed by watching or listening to too many conservative media outlets).
You can't "fix" or communicate with someone who refuses to listen or pay attention and respond in a meaningful manner other than repeat the same (parrot) rhetoric without driving yourself nuts and eventually realizing it's pointless and hopeless.
The same as is said about bullies in school: Ignore them. Eventually they'll go away, fall in line (need attention, parrot normatively), or get caught in their own trap (talk themselves in circles until blue in the face and suffocate themselves in parroted, self-loving, auto-erotic asphyxiation). But, if you feed the beast, it will remain and torment you until your dying day (including one's own need to argue with and "fix" or communicate in hopeless parroted rhetoric). AND, the longer you stay in this zone, the more you become like them...
Sounds like someone has been in my comments section:)
