This is actually a pretty good video. I agree with the presenter overall.

Graham Platner has a problematic past around Blackwater and his tattoos from his military days.
He says some good stuff nowadays
It feels like he's probably lying about not knowing his tattoo has nazi connotations. Even if he didn't know when he got it, he probably did some time in the last many many years, and chose to keep it.
He kept his tattoo until now probably because he didn't care enough to remove it.
Graham Platner is probably not a nazi wearing a leftist coat, as evidenced by his Reddit account over the years.
Even if Platner is being honest about his current views, it's best not to give the right anti-Semitism ammunition, and instead pick a different, better candidate (though granted, I don't know how available those are).
Personally, if I was in America in his area, I'd vote for him over most republicans, and some democrats, but it would be better if someone else was put forwards.
Funnily enough we have a similar potential situation in the UK, some people have been pushing for our prime minister (president equivalent) to step down and be replaced by Wes Streeting.
Wes Streeting is a gay man who is currently the Secretary for Health and Social Care, and is widely hated by the LGBTQ community for being transphobic, which is especially bad for someone who has control over trans health care, and has been effectively making it worse.
Just don't come to the UK right now, it's getting worse and worse at the moment for trans people.
The rest of western Europe is better for this, with many having self-id laws (I think you can change your gender legally without any procedure or having to wait for a doctor to approve you).
Whether you'll get a visa is another question, but a good start is going to study for a degree to get your foot in the door.
Alternatively, for Americans I hear Canada is a good choice, at one point they accepted LGBTQ people on refugee status from America (what a time we live in). Not sure how easy / hard that is to get.
