I agree, but anyone who opens a conversation with “fuck you” is not worth engaging with beyond responding in kind. They either know they’re wrong and have nothing better to say, or their mind is made up and attempting to convince them otherwise is a waste of time.

And I say that with regards to myself, as well. If someone wants to spread bigotry and hate, I don’t owe them civility and I am not there to embrace their perspective, so “fuck you” seems like the appropriate opener at times.
