Starting off with a premise that is nothing more than a broad generalization isn't helping your case.
Broad generalizations are always false.
Women aren't generally shorter than men, are they?
Men aren't generally stronger than women, are they?
Democrats don't generally accuse Republicans of being "racist" and "fascist" and "greedy" and "mean-spirited", do they?
Atheists don't generally mock and ridicule Christians as being "anti-science" and ignorant, do they?
My case is to speak the truth. Obviously that disturbs you. It disturbs a lot of Leftists who are enamored of themselves. I am nothing. My points are all I wish to make. Leftists attack me personally instead of pointing out errors in what I have to say. It's always the Fallacy of the Ad Hominem - the person making the statement!
The OP is about atheists as a whole, on average. It's not an ad hominem attack because it's not a person, but rather an entire huge class of people, like women in general. Like men in general.
You had no case to make and you still failed. What are you, eighteen years old? Or do you just act like it?
