It's not about changing that persons mind. It's about maximizing the value of the event for the rest of attendees.

And no, on politics. Differences of opinion on how to run a country, where to put resources, what policy makes sense. All fair game. Whether or not a gender or minority has access to the same rights as everyone else? Not political. That's a matter of human decency. The very bare minimum to begin to enter professional ethics.

Rest of the attendees includes many other Trump supporters, who have all right to be there and shouldn't have to fear getting kicked out for admitting it. You seem to imply that Trump supporters either don't exist or don't matter - whether or not people of some political party affiliation have the same rights as everyone else is just as much part of professional ethics as the equivalent thing for gender or race. This political filtering seems a bit like a repeat of McCarthy's Red Scare.

Nonsense.

Regarding the event: the mere discomfort of some people does not grant unlimited license to disrupt an individual's ability to conduct business and participate in society. As I've said elsewhere, I am not a lawyer but this looks an awful lot like tortuous interference.

Regarding politics: Whether abortion is the murder of a most innocent human life or the expression of women's sacred bodily autonomy runs right to the core of morality, ethics, and human rights (the mother's and the child's). And yet, it is also obviously a political issue. Trying to play word games isn't going to solve the problem that you share a society with people who may profoundly disagree with you.

Can you link where Trump has acted or said something against people of different genders or minorities not being allowed to have the same rights.
