It was a personal opinion that many disagree with.
I shouldn't have to convince you to be respected. I have other things to do with my life than gather together a compendium of research on porn. The truth is out there for all to see. You can find it yourself if you want to. The thing is not malicious, it's just an alternative opinion. I don't stand in your way, you are free to live your life as you like. If I condemn a thing you want to think is good, you don't need to take personal offense, just politely disagree and let's all be on our ways.
EDIT: I'm truly curious to see this one get downvotes. Do you guys really want people to call you out on every opposing opinion and make you run to and fro gathering a corpus of data, anecdotes, and other evidence to support every claim you make? I just don't have the time for it, and I don't have the interest because I know that I won't be changing any minds here, it'll just get written off with, "Well that psychologist/victim/whatever is a religionist so obviously he's backward", etc. Be sensible here, please.
> I shouldn't have to convince you to be respected.
Here, like anywhere really, respect is definitely earned. To make a broad statement like you did without supporting argument you are going to need "respect" for your experience in the field.
For example Tptacek can make pretty broad statements about cryptography/security, Patio11 about business/startup etc. etc. without much clarification because we know their expertise is supporting the statement.
Yourself we know nothing about; except you consider pornography a problem on a level with drug abuse. Which is definitely not going to put your comment on a good footing to start off with. It sounds personal - and while we can respect you feel strongly with it the way it was presented is discouraged.

There are some problems here. Firstly the main problem downvoters will have had is how sweeping your statement was with no supporting evidence. You didnt even add "In my opinion".... presenting a theory without evidence is frowned on here :)
Secondly the statement is worded in a way that suggests either your trying to cause offence or trying to brand people who might think porn is ok (probably the majority actually) as bad/imoral/wrong/ destroying their families.
I hope that helps :)
