got into some heated messaging with a member whom I denied friends` request

it turns a little ugly, I guess I should just deny his request without a message, but because he actually messaged me first and I did not realize that until I denied him, I apologize for denying him, and then he immediately replied that i am 'very friendly, just like the site' !!! I did not expect that reply, think he will just disappear, so I actually wrote back and explain his profile is not true nudist certified (not to mention his profile does not even has a lot written, and it contains just a chest photo!!) and I immediately updated my profile in details to avoid similar embarassment in the future. yeah I admit that I like to see photos of other nudist, and I am sure many of us here share the same desire, what is wrong with that? upon receiving my message, he shot back and claim he has been naturist for over 2 decades, he is an accountant, this and that, and he does not need to prove anything. he went on to suggest many people have issue of trust and other hidden agendas on this site. Hello??!! did you even read my profile prior of accusing me??!! Of course I do not take it lightly, I shot back and say he is certainly not trusting this site enough and avoid certifying true nudist to the administrators of this site, and he should take things easy, he then replied one last time and ask me to stop responding as he will not read. obviously a lot of lesson learn very early on for a newbie member on this site like myself..but I ain't an innocent kid anymore. just what have I done wrong to deny friend' request to a suspecting profile? is it because I take the time to reply and apologize for denying him? I have lengthened my profile extremely now, hoping this will not piss people off. english is not my first language, so I apologize if anything i wrote here or on my profile may offend others. hey if you have similar experiences like mine, or if you think I should have reacted differently, let me know what you think.
