which one is it?

Question

if you like A but not B, you say that you are

bias against B

or

bias towards B

Answer 1

against

Answer 2

bias against b would mean you hold to a truth or an idea or opinion which runs contrary to b's philosophy or identity or person etc.

bias towards b usually means you show a favoritism to b that you are not showing to A whether it be to b's liking and /or to a's detriment.

At least, this is the way I understand it.

Answer 3

against... if you were towards it would mean you were for A
