Hi, I am a registered Democrat, and personally I disagree with a lot of Trump's policies.

I think his foreign policy approach was dangerous and places the lives of Americans in danger. I think war with Iran would be disastrous, unwinnable, and lose too many lives, and so I oppose his aggressive actions there. I think he has weakened our alliances through unilateral action and a rejection of international agreements. I think this makes a withdrawel from these international groups makes conflict more likely, and prevents cooperation (although, I will give him credit, I did really like Trump's strike on Assad's airforce base in 2017). Having multiple childhood friends in the military, I worry about their safety if we were to enter a war with Iran, and I was particularly worried after the airstrike on Soleimani.

I dislike his opposition to changes needed to fight climate change. For me, this is perhaps my biggest issue. I would literally let a candidate slap me once a day if it meant we could achieve carbon neutrality by 2035 (and maybe once a week if it was 2040).

I oppose his tax cuts for the ultra-wealthy, and his cutting of funding to programs to help the poorest Americans (such as foodstamps). I dislike his changes to allow LGBT people to be denied medical coverage, and a general undermining of LGBT rights. I dislike that he has tried to remove Obamacare, a program my niece depends upon to live, without a clear alternative suggested.

I dislike his immigration policy. I had a Syrian friend who had to go home for a family emergency, and not being sure if she would ever be allowed back in the country was really devestating. I have friends from Somalia, Iran, and Iraq who all were seriously affected by his "Muslim Ban". I personally am an immigrant, and I support a more accepting immigrantion policy (which also I believe will help grow the economy), so his restrictions on visas, and the reduction in refugee programs I strongly oppose.

I opposed his crackdown on BLM protests. Seeing the footage of excessive police brutality during the protests really made me angry, and hearing stories of friends being tear gassed while they were peaceful, and everyone around them was as well further angered me. Also, I do think his whole approach inflammed the situation (I have done some studying of riot control and crowd psychology, and the confrontational approach Trump took is far more likely to make protests become violent).

The one policy that Trump campaigned on that I was a big fan of was his $1 Trillion plan for infastructure, but it frustrates me that this never happened (I could go on for further Trump policies I dislike, but I think you get the gist of it. I am happy to elaborate more if you want, though).

Still though, I don't hate Trump supporters. I think generally there is a lot we have in common, and we often have the same issues (increasing power of corporations, low quality of life for the working class, disappearing of the middle class, opioid epidemic). There is a lot I really dislike about the Democrats too, but I personally think they are still better than Trump on these issues.

Anyway, happy to answer any further questions you have!
