No, being respectful to a place is quite simple, you just struggle to get your head around it evidently.
Respect has nothing to do with snobbery or obnoxious.
And it’s not just a forest, it’s a forest where people go to suicide, that’s the reason OP wants to go and that’s what the place is famous for, he isn’t going there because it’s a forest, he’s going there if it’s reputation of the suicides not to pay respects to the dead but to get a kick out of it.
That’s disrespectful.
How hard is that to understand.
My reason for going there is my brother will be the driver and wants to visit. If he’s hell bent on staying overnight then I would have course support that. If that how it goes I may camp or even find a place nearby to stay. Don’t fancy a night in the car so it’s one or the other.
