If I drive by your house and there's a Trump banner and a swastika I draw conclusions. You have told me enough.
In your case you would say that's not your opinion... It just a flag. Like you didn't post that African countries were shit holes.. you just posted an article claiming that. Because that's a real difference.
You're not really a white nationalist... You're just posting interesting stuff, like the pretty red flag with the swastika doesn't mean that you're a hateful bitch. That's just my bigotry showing .
