That's what i would actually say. If you know me well, you should know what i like to say: Different people has different opinion, so no need to get mad about what people says. Why am i saying that, because what i want to add on might offend some of you.I dont totally like them but, if you find somone you like online why not try for it. You might accually get somthing out of it.
I don't like dating online either, and i don't even think that's a good idea but mostly it won't work out like one person stated "how can you know the person's personality online?!" That's true, who would know that person's personality through online, even if i'm dating someone in real life, i might not know everything about him, right? Then why risking online?!
As the person i quoted has mentioned, "if you find someone you like online why not try for it." Yeah, go head if you want to try it, go for it. We can only suggest not to, but we can't stop anyone. I believe this is what this person (the one i quoted) think too.
Most people would fail online relationship, but that would go into your experience record, or it could be worsen. So if you wanna do it, go head, but don't regret, because people around you are not going to get involved or responsible for it.
