Tu quoque

From wikipedia:"Tu quoque (Latin for "You, too" or "You, also") is an argument that implies that a certain position is false and/or should be disregarded because its proponent fails to consistently act in accordance with that position; it attempts show that a criticism or objection applies equally to the person making it. It can be considered an ad hominem argument, since it focuses on the opposite party itself, rather than its positions.For instance, "Reverend Bob claims that theft is wrong, but how can theft be wrong if Bob himself admits he stole objects when he was a child?"If there are mistakes in hinduism or any other religion, how does that make islam perfect. Just because muhammad said so in quran (not god, for sure).Only islam claims to be directly from god, the only true religion.
