How do you expect,

To not be hated when you also are also hating?
To not be ridiculed when you are ridiculing other people?
To not be belittled when you are belittling other people?

To have someone be nice to you when you aren't even nice to other people?

As the old saying goes,

"Treat others exactly how you want to be treated."

You cannot belittle someone and not be belittled by someone else back.
You cannot hit two birds with one stone.

Trying to catch two hares at the same time (as in AT ONCE), will end up with no hare caught at all. Unless of course you are extremely skilled, but I highly doubt it.

I have yet to meet someone like that.
