May peace be upon you
In general sites like Answering Islam, all they do is try to find things which they can criticize Islam with, which frankly, sometimes can be really laughable, like I'm sure you heard of the claim that Allah is a moon god. As you can see, they can take out anything and call it a contradiction and make any ridiculous claim about Islam.
In the Quran it says
031:006
"But there are, among men, those who purchase idle talk, without knowledge, to mislead from the Path of God and throw ridicule (on the Path): for such there will be a Humiliating Penalty"
The point I'm trying to take is, its possible to criticize practically anything, and reading them has a negative effect. When you're sure with Islam now, if you read such claims, it sounds ridiculous, but if read enough it could affect you, making you start believing them. So personally I would advice you, not to really go through such websites, which is a waste of time and hinders your faith.
