NON-JAPANESE(remember, we are ALL foreigners when not in our native country)people with this attitude put me off from wanting to associate with them, but I am assuming you already knew that because you're either trolling, or see what a bad idea it was to post something like this here since you haven't responded.
Granted, if you're at a Japanese dating site and you're not Japanese, wtf are you doing there, but as someone else mentioned, you can just ignore it rather than throw a tantrum because you disagree with it. If a Japanese person were to see this post, they would find you and all other non-Japanese people unappealing, because they can't understand why "we" hate each other so much even though we don't know each other(and therefore, have no reason to resent each other's presence). There are instances where ignorance is bliss.
