Wow, I have not known ragdolls to be so aggressive in that way?

I personally have a low tolerance for that sort of behaviour from pets. If he is & has always behaved this way with you (is it just you or would he do this too DH also?) then he needs a good kick up the bum & put in his place.. Problem is, you can't really kick him up the bum LOL. Cats are different, its not like you can pull him into line with a good obedience training programme like I would suggest with a dog.
He is trying to be the dominate one & he is going about it all wrong. If it was me, he would live outside permanently (but then you may find the neighbourhood hunts you down to cover the vet bills for the local cats he is bashing up) or just get rid of him. Im not one for passing on problem pets so you would need to send him to a place that will assess his suitability for re homing. But honestly if he displaying such aggressive behaviour he may get put down. I would do as suggested above & look into a ragdoll rescue mob (if there is one local enough to you) or contact the RSPCA & talk with them about your options.

But in all honesty he sounds like an ******** cat that needs a good slap LOL
