It's a psychological fact that no one can be persuaded by a debate on issues they stand firm on, regardless of what or how it is presented.
So I don't even try, I just clarify issues where needed or poke the more rabid devotees enough to get them to blow themselves up.
Most of the Trumpers are here to do the same, to irritate voices that differ.
The few that aren't, if they are willing to engage in decent conversation with you, then by attacking them you succeed in proving the trolls who have previously provoked you right, or at least reacted in a way they wish, which is by losing your cool.
Not saying hug it out, but discussing and listening works for us all.
