There isn't a single "complaint" in the paragraph you refer to.
If stating the factual matter of what you can do with or against crypto is "rude" to you, feel free to not answer next time, as your whining/concern trolling won't change much to these facts... especially when they don't relate to what was debated: reversability of transactions.
also perhaps consider taking a less passive aggressive tone. throwaway accounts are not an excuse to be rude
