It's the same situation as any other individual. To be general it all depends on bạn if it will be hard hoặc not, and also depends on the situation your in in life.
I don't think that for Goths it is harder to find the true love. No, they don't have to finde tình yêu to be a proper goth themselves. Why should they?
If bạn are really picky, which basically means that bạn have to ngày another goth, it could be a bit difficult. Simply because the tổng thể human population is not goth. But still, I guess that they are enough goths around to date...
On the other hand, if bạn want to ngày a non-goth, it could be even thêm difficult, because not every non-goth would accept your "gothiness"...
To your một giây point: no, bạn do not need to have a romantic partner to be a "proper goth" hoặc just a "proper human being".
P.S: "True love" is a vague term. I'd like to think that is exists, but I tend not to believe in it.
maybe... Personally a had a situation when a boy who I liked told me that I am frightening. But I think that someone who couldn't accept my style couldn't be a really good partner for me. But I belive that if someone (even if she/he is a goth hoặc not) searches really hard she/he will find the True Love. :)
