The swearing is something that makes sense when it's a situation to swear. I would not trust person who never, under any circumstances swear.

The same thing would apply to a person who swears endlessly without reason.

Here, on the other hand, someone is trying to force his opinion on public. This, I can judge. Both on merit, and the language they use.
