Thanks for your response, I'm not the OP but I'm similarly trying to understand the reasons for Trump. My personal belief ( and talking with some of my own circle of friends that supported him ) leads me to believe it's a few thing:
1) the tough talking, america first attitude. I think this attracted a number of people simply due to the 'feeling' it gave them.
2) the desire for change. anti-establishment, anti-washington, anti-'what was before'. this was seen in Bernie's rise, and Brexit. so it almost didn't matter what Trump did or say at that point, he was the messenger of change and people were hungry for it.
3) blue collar workers & economy. If you feel like you've been left behind, and the govt isn't helping, well Trump's message definitely resonated better than HC.
So those are a bit of what I'm sensing at this early stage of my understanding. I'm sure more will reveal itself throughout the coming days, months, years. However, to your specific points as to why you supported Trump:
1) Trump is easier to predict? I find this truly hard to believe. He is almost entirely unpredictable at this point. He ran on the Republican ticket, but he's hardly your standard Republican. He says he's not free trade, yet wants to do things to help big business, yet wants to impose huge tariffs and taxes on businesses that outsource and offshore to save money. IMO, these are somewhat contradictory. I honestly feel like Trump just echo'ed the anger of a certain group in the country, regardless of what he personally believes, or thinks he can implement.
So on the case of predictable, I disagree strongly.
2) Clinton has been hawkish in the past, and generally leans towards US intervention, I'll give you that. However, there are also examples of her using actual diplomacy to achieve results ( Iran deal, like it or not ).
Trump has said some really outlandish things as it comes to foreign policy. Encouraging the proliferation of nuclear weapons, abandoning our allies, letting certain parts of the world fend for themselves. I personally think there's a fine balance between being imperialistic and trying to keep the world peace. To say it's China's problem to deal with North Korea, so South Korea/Japan/Taiwan can go fend for themselves is a very narrow view of the world. I think this type of inward behavior actually leads to bigger/larger potential wars down the road.
3. Illegal immigration, OK clearly he built his platform on this. But this is again an issue where nothing with him is clear. He never presented a clear proposal no what he intends to do on immigration besides being tough and building a wall. And to say HC wants sweeping amnesty is inflaming and misleading the debate rather than moving it forward.
4. This is just strange to use this as a reason for Trump. I mean he said a couple things on LGBT, but if you follow this through his SCOTUS noms will play a huge role on the rights and privileges of that demographic going forward.
I certainly am not trying to bash your entire premise for Trump, like I said in the beginning I am trying and reading to understand his rise, and some of it is becoming apparent.
And I do hope he leads from the center and backs away from his more extreme views. And I do hope he succeeds as a president. But I am honestly confused by some of your points, as much as they might match with his campaign rhetoric, they do seem to crumble upon examination.
