I've made so very many liberal political memes in my time that I have a lot of in-built psychological resilience to actually going full Trumpist. Hah.
But I agree with what you're saying. I've noticed that making right-wing propaganda myself has a different psychological effect than merely scrolling past it day after day.
However, it's not necessarily a bad thing. I know what you're thinking, but hear me out - it has helped me see the other side as human beings rather than brainwashed Trumpist mind-clones. Really, it has. And equally important, it's helped some of the politics streamers start to see me as more a full human being. It's weird that something like that is what it takes, but in our hyperpartisan era, where the other side is constantly demonized, I guess it is.
I do think that being able to relate to our fellow countrymen across the aisle is more important than the exact level of taxes or the price of gas or whatever. Because if the political divides in this country continue to exacerbate, then we're heading for a Civil War or best-case scenario, a peaceful negotiated break-up. A Civil War would be unthinkably catastrophic - a partition, incredibly depressing, disruptive, and still potentially violent (see the violent partition of India/Pakistan, and then the later partition of Bangladesh/"East Pakistan" from the rest of Pakistan).
Heck, we're seeing it right now in the U.K. with Brexit having torn internally at the divisions between England and the other countries, esp. Scotland and Northern Ireland, in a way we haven't seen in my lifetime. It's quite possible the U.K. will break up somehow. In the U.S., Texas has been threatening to secede for ages, but this time it might actually happen and some other states might decide to go with.
All this is avoidable. Nothing in history is "inevitable." But if we want to keep our country, we have to do hard work to make it happen, work we didn't think we'd have to do.
