Is Trump still anti-Arab and/or anti-Muslim, or has he changed his tune?

Are you asking whether he is:
- openly anti-muslim; or
- personally anti-muslim?

If you recall Trumps early foreign policy (or anything 'not American') phrasing, I think you have a good idea of who Trump is. He's improved a lot in international statesmanship since (though whether that is up to the level of a President is a matter of opinion)

Publicly anti-Muslim.

We know Trump has a history of being publicly anti-Muslim:

Please give an example of Trump's "early foreign policy (or anything 'not American') phrasing". Are you referring to his policy before or after he became president?

Keh, foreign policy is only ever used in terms of politics, and he wasn't a politician before he was president.

As for examples on his early poor phrasing relating to foreign policy - I'd be surprised if you go around collecting links to articles on what a person said at any given time, so why you expect me to, I don't know.

In any event - I found one relating to a speech he gave in Saudia Arabia that had cringeworthy moments

I also recall a report of him berating a foreign Prime Minister , and what it related to:

I vaguely recall some odd ball insulting comments on China that could also have been more diplomatically put, but can't find any reference to such.

This of course was a couple of years ago, and my main impression was that he really, really needed some lessons in foreign diplomacy.

My impression since, is that he's improved in this regards a great deal since.

That is not a comment on other aspects of his presidency, nor a comment on his ideas relating to tariffs and walls.
