Do you realize this is a false dicotomy. You can have a motorcicle and be kind and be formal while being unkind.

The idea of the "bad boy" is usually quite superficial because many men who complain about women dating "bad boys" aren't paying attention to those men actions and their own actions. Many times those men that are called "bad boys", treat women well, while the "nice guys" treat women like shit.

So yes, you might want someone kind in addition to have a motorcicle or whatever preference you have. Those aren't incompatible.
