Well, I don't want to speak for Raiden but I think they were more just saying that if the very mention of the existence of Valentine's Day bothers you, it's not that hard to ignore the thread. As you said, you're not particularly bitter and you treat it like every other day. If you think of it as some insulting day that the mere existence of tortures you, you might wanna just steer clear of the thread about it. Let's not fight, I'm pretty sure it wasn't meant to be insulting.
