So Avoid Treating the Other As the Enemy.

It's a two-way street. Most Repubs and Conservatives have tried to treat others as individuals, whereas the Dems and Liberals treat EVERYONE who isn't a Dem or Liberal as a Racist and a Nazi.

Dont conservatives like you call anybody who isnt a republican commies? or with a different opinion?

Show me one instance, just one , where I have articulated that sentiment.
Let me save you some time...you can't, because I haven't.
I have called socialists Marxists, I have called Antifa NAZI'S, and I have called BLM a racist organization. All of those statements are demonstrably true.
I will continues to do so when anyone or any group exhibits those tendencies, even someone who identifies as a " Republican" or a "Conservative" ( as I have frequently done).

Some conservatives call all democrats commies and nazis that don't agree with them(I'm not saying you I'm saying some)

As long as people play the " what about..." game we will continue to be at each other's throat. What we should be doing is finding things we all agree with...such as it is wrong to judge anyone based on something they have absolutely no control over, the color of their skin.
Also, we should be able to all agree that America is still the best country in the world...not the most perfect, but still the best.
