Is it bad to find BL/GL character attractive?

(i feel like i should start with i am NOT cis. I am just trying to make sense of what i heard)

Ive seen a lot of people saying
“You can’t find _____hot because they are gay”
or
“They wouldn’t even look your way irl “

Aren’t they just characters? They are DRAWN to be attractive.

Is it Bad?

I thought as long as you don’t bother real people I don’t really see the problem. Though maybe i’m wrong(￣∇￣")

Kinda unrelated but i’ve also seen “don’t get turned on by *BL or GL* if you’re [cis opposite gender]”
If you’re reading literal porn why wouldn’t someone get turned on T_T
