I agree that this is a possibility and a risk, but I think that a bit of common sense goes a long way. One of my classmates tried to frame everyone who disagreeed with him as nazi, but nobody fell for it, because it was obvious that he just tried to evade criticism. There also needs to be some leeway - for example a German court has ruled that a public service worker could not be fired for calling his boss an "old asshole", because they've known each other for very long. Context matters.
Most, if not all, meaningful speech risks offending someone.
Framing uncomfortable beliefs as attacks grants a form of "victim power" by which anyone can claim to be a victim of your "attack" as a means of shutting down speech.
This isn't a hypothetical, I see the technique used frequently.
