Posting glass pipes for sale here, even with the 'do not use for illegal purposes', seems like you are really pushing the envelope. If the site owner or staff do not wish to deal with any possible consequences of these types of sales, either real or perceived, it is unfair to expect them to do so. What if, for example, the site owner decided he'd rather not allow any for sale section than risk a lawsuit over what is sold through his site? Would we all still be behind the OP's right to sell his glass pipes then?
And no, Im not prude about pot, pipes, or what ever you want to put into your body. So long as you dont harm anyone else in the process. This is not about being for or against recreational drug use, its about pushing the envelope because someone wants an easy way to sell his stuff.
And acting surprised this caused such a stir does not lend me to believe the genuine attitude of the OP. *shrug*
