Responding to a blog post that was linked on an external forum with a different viewpoint isn't interrupting; it's kind of the whole point of having a comment section. They're sad, other people don't think it makes sense for them to be sad. You can respond to that disagreement with an analogy, and I can respond that I don't think the analogy makes sense. There's no obligation for people to only respond to an article with viewpoints that agree with it, and sometimes lots of people will think that the take is out of touch for some reason.
