I would argue that even the bolded statements are, in many cases, incorrect.
Not really. They just have so little importance that they can be applied to any two diverging viewpoints.
Going over them individually.
1. You Can Do Terrible Things in the Name of Either One.
Mostly true. Anyone can do anything "in the name of something." It's entirely possible for a person to go out and kill a theist "in the name of atheism" because they want only atheists to exist. Likewise, I don't have to explain what's done in the name of religion by radicals.
2. Both Sides Really Do Believe What They're Saying
True, unarguably and axiomatically. People believe what they believe and what they believe puts them under that label.
3. In Everyday Life, You're Not That Different
Pretty much true, though the more religious one gets the more this differs. In your job, at the supermarket, driving to work, taking a vacation, talking with friends...well, there's going to be far more variation between individuals than an aggregate group of atheists vs theists.
4. There Are Good People on Both Sides
True. There are plenty of religious people (the majority) who do not use it to harm other people and do good things. There are plenty of atheists (the majority) who do not rage about religion all day long and do good things.
Though this one seems more for the theists, who commonly argue that atheists have no morals.
5. Your Point of View is Legitimately Offensive to Them
Okay, this one might be untrue. I don't find the idea of theism offensive. I don't know how many atheists do. I do know that a lot of religious people find it offensive to have it said that what they believe is not true, so I lean more towards this being true, because I know many atheists find
religion offensive and I do as well.
6. We Tend to Exaggerate About the Other Guy
Change exaggerate to generalize off extremists and this is 100% true. The idea itself is true.
7. We Tend to Exaggerate About Ourselves, Too
Do I need to talk about how unrealistically people can view themselves and those in their group?
8. Focusing on Negative Examples Makes You Stupid
While I would argue that it makes you stupid, it certainly is intellectually dishonest to not look at the whole picture. Only talking about the good or bad of anything presents an unrealistic view.
9. Both Sides Have Brought Good to the Table
Again, true. Atheists and theists are perfectly capable of doing good and contributing to knowledge and peace.
10. You'll Never Harass the Other Side Out of Existence
This is an observation of human nature. The more you try to repress something, the harder it holds on. "Harass" I take to mean not commit genocide but bother incessantly, so true.
