I was a simple-minded **** at one time. I thought the Civil War was about slavery. And the first time I saw anyone wearing a Confederate shirt, I thought "Wow. That's pretty racist(except I didn't know what racist meant, I just thought it would offend all black people so I didn't have a specific word). But then I took the time to educate myself.
I was in first or second grade so the resources were far more limited than they are today. There's really no reason for a grown man to be so stupid.
