This is true. I had to look over the last few comments and the payload is here:

>> Even if he has [harassed someone], that doesn't invalidate anything he's saying

>I just don't think there is ever a good reason.

If you'd have said 'I just don't think there is ever a good reason to be rude or demeaning' then people wouldn't have made the link to harassment. Or even address the word harassment explicitly.

Either way, the points were getting conflated.
