Unless you know the details of the argument, it could fully be a result of the protest.
Actually I DO know the details of the argument and it had nothing to do with the protests.
That is why I made the comment that I did - the OP, without knowing any details, immediately blamed it on the wrong group of people, which is what Trump supporters were, rightly, upset about during the campaign...being accused of saying or doing things they hadn’t done!
We have to be better - NOT sink to the same name-calling, uniformed tactics!
