Maybe bigotry is the wrong word in this case, but maybe not. Either way it's still discriminating based on an unchangeable characteristic of those people. I'd be equally annoyed if they targeted men or a specific race or an eye colour. I just think that when you try to help people, you should try to discriminate on circumstance, not things like race or gender. And we should be calling it out so people can do better in the future.

I do know there is a lot of correlation between gender and circumstance, but I think it's either lazy to use gender as a proxy or they really are bigoted.

On the other hand I would still like to give them props for helping people in a significant way.
