I don't. Counting as my friends are people I can actually talk about politics with, at least to some degree. Otherwise we're talking family, colleagues or acquaintances.
With one of these three groups whenever the topic moves to how much Trump is AstroHitler I make no mystery of my contrarian perspective, because fuck the retards, we don't have the time for that.
My approach:
1. Defusing the elephant in the room. Muh le racist Trump. Everybody is losing their minds because Trump wants to actually enforce immigration laws in the US and this is like a trigger to go full hysteria Hitler. I take no gloves to hammer that point. Works every. single. time. No one can counter-argue in good faith with that, the racist meme doesn't hold 2 seconds in front of facts once they've stopped screaming and the topic moves to another Trump issue 100% of the time.
2. Addressing the sexist meme (always comes off as The Stigma, after racism of course, gotta admire the efficiency of the Left to make that happen with 10 secs of shit-tier decade old video). Nowadays I just start with bluntly stating all the accusations of sexual assault are utter, absolute bullshit. This generally triggers the hell out of normies who wow just wow and can't even, until I point the timing, the facts (most of them are already debunked by now) and demand some hard evidence for the basis of the accusations, which I have yet to receive.
3. At this point I generally counter-attack to put the pressure back on them with ironizing on muh polls who say the election is over already so why even bother, or with pointing out one of the latest hot files on Hilldog. It's getting much easier with all the evidence of corruption Wikileaks and O'Keefe are uncovering lately, as it makes the bottom line "Trump may be flawed but look at the system you're supporting" way easier to defend.
Now don't get me wrong, normies are so brainwashed that the idea that Trump might not be the Antichrist and that Hillary isn't exactly the perfect candidate is very hard to swallow. It is almost impossible to convince a shitlib that is not already on the fence to some degree. A large number of them won't even believe you're actually supporting Trump, the cognitive dissonance is too high for them. However, you can get rid of the pressure, throw it back at them and plant small seeds of doubt. Time and happenings will do the rest, or not.
Bottom line is, racist and sexist is mostly what holds the PC fortress together, and without having their little mental edifice collapsing at once you can at least start blurring the lines. I have yet to meet someone who lost their mind against me after such a conversation.
