It is better to be able to substantiate your opinion with evidence.
Talking points are not facts, nor are closing arguments, they are emotional appeals.
if someone disagrees with your stated and unsubstantiated opinion it does not reflect on your point of view.
it does however reflect on your reasoning.
I am often times called a trumpster, even after repeated anti trump rants.
today I am a white nationalists even though I am of Hispanic descent.
There is no evidence that Trump is a racist in his actions. Just talking points promoted by nefarious actors.
generally I posted a wall of text or a link to underpin a position.
if your position is solid you can find supporting articles. if someone points out another article that differs in conclusion that is debate.
if you only want talking points watch MSNBC or CNN
