Why do some people even bother to click on questions they hate to answer? there is no compulsion on yahoo....?

yes u r absolutely right; they are none other than cowards who doesn't even dare to come forward.But remember, their actions should not stop u from your motive.Actually their motive is to stop you from spreading Islam;coz they are among those who are creating misunderstanding among people about Islam; coz they know that Islam will open their minds towards the reality. They fear that people will revert to Islam.
