I respect your point of view but I am not going to make an effort to send someone a message to reject him. To me, that is unkind. I would rather not respond. Plus, on-line dating is scarier for women. To me, they are all total strangers. I don't know any of them personally and if I don't feel any interest I would rather just leave it alone than get to know someone personally who I know I'm going to reject just on the basis of lack of physical attraction. This is one of the reasons I don't like on-line dating. It does make people shallow because seeing their picture and profile gives very limited information plus I find it impossible to figure out if there is any chemistry on a website, and there is too much pressure. In real life you can be acquaintances with someone with no pressure to become more, friends with someone with no pressure to become more and if it happens, it happens and if it doesn't it doesn't. No big deal. On the internet there is the expectation that if you talk to these people you are going to date them and they don't want to be friends. And I see the world of on-line dating as a whole lot of complete strangers in which there is no established trust, I take a risk every time I give my phone number to any one of them, I don't want to be in the awkward position to send a rejection message, so I will only have a conversation with an on-line stranger looking to score a date only if I feel at least some level of interest.
