To love them? No, not difficult, if you happen to be gay. It's perfectly natural.
But to be gay, in a world that isn't quite ready to accept you - that's not all that easy.Depending on where you are in the world, you can be accepted, but in other countries in the world, you can be imprisoned or killed for being homosexual.
If you happen to be a lesbian in some of these countries - you could be subjected to what is termed "corrective-rape" - rape to "make" you straight.
Even in your own family it could be difficult - if they are anti-gay, very very close minded, extremely religious etc. Coming out can be very hard, and very difficult.
But for some it's not. It can be easy if you have accepting friends and family and lots of support.
Loving is easy. Being an authentic version of yourself isn't always.
