Minor note- the phrases “nothing personal” and “no offense” can often have the exact opposite of the intended result. Tthey can come across as condescending and very often when people use them they really are trying to be offensive, although they may not realize it. (A relevant quote from me from about 10 years ago “No offense, but the only thing saving that argument from being completely stupid is that sections of it are incoherent.” (Yes, I’d like to think I don’t say things like that now)). And “in my opinion” is very rarely useful unless the point being made is that one is a subject matter expert. It also personalizes things unnecessarily in the same way that the 2nd person does, just to a lesser extent.
