I said "I'm not arguing that they have any good points or that we should give them a platform."

Also, admitting ignorance doesn't mean I have "no idea". I've read a bit of psychology on this topic, and feelings of being rejected by society are very powerful motivators.

Just for the record here: I think it's a good thing when people are willing to admit they're ignorant about certain things. It shows that they are willing to learn and change their minds based on new information.
