I still think Trumps tweets -- the Tweets I read with my own two eyes on twitter -- about the 4 women clearly express a strong nationalistic sentiment (I think it would be difficult to refute that) and are at the very least racially charged - ok, but we must consider the context to those words. The context is that Trump and the 4 women are having an ugly war of words. Again, one of the women (I think it was the Palestinian-American) started her political career with 'let's impeach that MF.'
If someone went up to some random person of colour on the street and said 'get back to where you came from!', well, that's obviously very different.
I don't know about Trump's other tweets (it might be useful if you provide those) but re Trump vs the 4 Dem women, there is a context to his words.
Do I think Trump's words are ugly? Yes.
Do I think Trump should modulate his future speech? Yes, that would be good. I've already said in a previous post that, although Trump's blunt speech may have been refreshing to some in 2016 when he was taking on the political establishment, such refreshing bluntness can quickly grow tiresome, plus these are tumultuous times for the US in 2019. Trump would do well to adapt.
Is Trump a racist? The jury's still out on that one. (Supporting evidence needed.)
