Twitter hides Donald Trump tweet for “glorifying violence”

Exactly. Not to mention that what Trump tweeted about has long been the single workable solution to widespread looting.

Protests are fine. Mayhem and larceny, however, are not. Violence against lawbreakers is absolutely enshrined as acceptable, and that isn't going to change for the foreseeable future. There is nothing whatsoever wrong with Trump's tweet, certainly nothing overriding the First Amendment.

Further, Twitter is absolutely in the wrong to portray itself as passing some kind of absolute judgement on the President's views, and in fact that it is above the Presidency. It is NOT a neutral platform.
