Telling someone, "or maybe you should learn JavaScript" is kind a really jerky way of saying, "you don't know what you're doing". I do think it was a terrible way to share knowledge. Yet it was an excellent way to say, "I know more than you".

I agree it is rather combative, however it's also true. To claim that X pattern is a reason to not use a library when said pattern is actually an anti-pattern you've used because of lack of understanding is going to garner these kinds of reactions.
