[This is what he re-tweeted.](https://upload.wikimedia.org/wikipedia/commons/7/70/Swastika...) It might be in bad taste but arresting him and insisting he undergo re-education is crazy, and I can't believe you would defend it. No one gets arrested in the US for re-tweeting memes like this.
As for the rest, you're free to call politicians fat idiots without being arrested in the US, and once again, I cannot believe you would defend arresting people for that.
