It doesn’t seem to make a difference.
Most people arguing about this are coming from an emotional place, so facts and truths don't really matter. If gender in language is important to your in-group, that's what matters. Not the history of language. Not the dictionary. The group believes this. If you reject your group, you'll die alone. Or that's what the brain would have you believe. We're all a little susceptible to social influence on belief. Some people are just unwilling or unable to overcome it.
Belief is social.
For many people, emotion is the only truth.
