The commenter somewhat retracted their use of this word in a sibling comment, but it seems important to me that we don't confuse strong views with zealotry. Drew's views are certainly very strong.

Strong views can be rational and well thought. I even believe they are often the ones that can push the world to a better place. Usually you can even argue with someone yielding strong views if they are rational (unless the person is bad at communication / is an asshole, of course it's possible). Strong views can shake you up and are not always enjoyable.

Zealotry is just plain irrational and dangerous and there's no way you can have a constructive discussion with a zealot.
