Keeping a baby or other options

I've read alot of things on here about when couples dont agree on what to do when they find out they are pregnant and it is unplanned.

When a girl wants to keep it and the guy doesn't alot of people respond with well then he is an ass or fill in the blank. It seems like people forget that it was both of them that created the baby and the guy has a right to his opinion on it as well. It may not be what the girl wants but he still has a right to express himself and his feelings which doesnt not make him an ass. If it were the other way around which i have seen an read, alot people dont necessarily bash the girl for not wanting to keep the baby and say do what you feel is right for you. In the end the guy has no say in either situation because its the girls body and she will do what she wants to do. So why is it ok to bash a guy for not wanting to keep a baby with an unplanned pregnancy or even expressing his opinion? In the end of either situation the guy will end up paying child support because of the girls decision or not have his kid because of the girls decision.

Im all for girls doing what they want when it comes to that but i think we shouldnt be putting down the guys for having feeling and opinions.
