I think it's retarded of girls to think that ALL guys are bastards just because they have had some bad experience with them before. These are just some things you could do to help yourself :

1) Just get over it
2) Because every guy seems to already be in the category 'bastards', you'll prolly be missing out on the good guys.
3) Stop telling the world how you think all guys are bastards cos it's just damn attention seeking. Like what are you expecting the people around you to do? Sympatise with you?
4) Go be a lesbian so then you won't have to deal with dicks ( pun intended )
