I agree with you on the use of racist, but I think slurs in general end discussion. For instance a liberal can’t critisize Trump with out being labeled TDS or “sore loser”.And babykiller, libtard, and commie.And white trash who are wrong and fundies who are wrong...you gotta reach out from the left too.
That's a start.
But until you give up on calling people "racist", it is small potatoes.
Along with homophobe and bigot.
NOne of those have the same impact as "racist" in our culture, AND, conservatives don't use those to attack the person INSTEAD of discussing the issue.
Hell, they CAN'T even if they wanted to, because calling someone a liberal does not marginalize them the way calling someone a racist does.
YOu can be a liberal, or a commie, and your argument will still be listened to.
I've often agreed with liberals on their criticism of Trump, specifically on the Wall, and Syria and Russia.
Not nearly as often as I've disagreed, but, it depends on the criticism being made.
I've often used slurs in such discussions, such as warmonger, trying to make a point. But it did not end the discussion. It was an attempt to make a point.
I'm not seeing slurs in general ending discussion. Republicans just don't have that ability. Libtard, does not have the cultural poison that Racist does.
