So... What "false insults" you find annoying?
FYI: A false insult is something that is NOT intended to insult another but still people take it as an insult for unknown reasons. (At least unknown reasons to me).
As for myself... There's two major ones I really dislike. The first one is "Ignorant/Ignorance"... Too many people take it as an insult, thinking it means stupid, but that is not true. Ignorance is lack of knowledge while Ignorant is a specific person with a lack of knowledge... Saying someone is Ignorant is really as bad as pointing out a typo/grammar mistake in their writing... FYI: You are pointing out a flaw. Plus the fact that everybody in this world is ignorant to something so it is only natural to be ignorant... So ye'h... I do get annoyed when people take that as an insult, especially when I'm just pointing something out and then explaining to them the knowledge they are lacking, thusly no longer making them ignorant to whatever subject it was...
The second one isn't really an insult but some people tend to take it negatively... It's the whole "That's a bias opinion!" type of thing, which I find extremely annoying... EVERY opinion in the world is bias and it is impossible to NOT have opinions so... everybody is bias. Though I should note that you can be extremely or calmly bias. Extreme is when you pretty much point out your side while calmly is where you try to hide it and try to work with both sides, though you are still bias as long you have a side.
Note: There are always at least THREE sides in opinions. The first two being "Red VS Blue" type of deal with the 3rd one being "Myself", if that makes any sense... I would lovely explain more if any asks.
Also... What do I mean about it being impossible to NOT have opinions? Well. You literally gotta have no sense, no feelings, etc to have no opinions which is impossible to live like so. (FYI: What you like to taste, feel, see, smell, etc are all opinions as well!)...
