I would pick which battles you want to fight on this.
All his views together are pretty grim. But looking at each one in isolation and you can possibly eradicate some and challenge others while ignoring others.
Trump is IMO an awful human being on so many levels. But the fact is that more than half of the American population voted for him. We can say that every one of those trump voters is a sexist, misogynist racist, but the fact is that many of the people who voted for him are women, and many who voted for him were from ethnic minorities. If we just dismiss someone’s admiration of trump as a load of bollocks then we’ve achieved nothing. Because there is a valid question to be asked here - why do so many people admire him?
It’s not as simple as just saying that all those people are all the above. There are additional reasons, such as promises Trump has made regarding the US economy, in a time when the cost of living is at an all time high and people want some hope to cling to. So they’re prepared to dismiss the talk of dogs and cats being eaten because those aren’t things which affect them personally. Many people are done with having children and so the abortion rights of others are inconsequential to them.
People will vote for the policies that matter to them while dismissing the rest which don’t.
The trans argument is here to stay for now, and tbh it’s best just to ignore, because it’s a battle that we cannot win, but will IMO fade out over time. But as things are now, most teenagers will go down the trans acceptance route. Almost every teenager will have friends who are either trans or gender neutral, and while people say that this is all about women’s rights, ironically the people I know who have come out as trans have all been women. I even know one who has had top surgery so far. Pronouns on emails are becoming a thing, but you can ignore that without actively standing against it. And generally as teens get older their views start to soften if they haven’t themselves come out as trans, and as they develop intimate relationships of their own.
The black/female actor/actress is an argument which has been raging for years now. Because positive discrimination means that many of these actors/actresses are being cast because they’re black/female, not necessarily because they’re best for the role. Of course in many instances they are, but it only takes one for that whole balance to shift in favour of the conspiracy theorists.
If he’s not open to discussion on any of the above then all you can do is dismiss his views.
The racist element you can keep your children from, but you’re not going to be able to shield them from the trans debate. In fact I would go so far as to say that your children are almost certainly going to be embroiled in the trans culture, if not themselves then through friends.
