Well the problem is the vagueness of people's motivations. You are strong in your beliefs and I believe you have no racism behind your booing so it would be unfair to label you as being one.I like Cyril for the things he does on the football field and not for his personal beliefs or view points.
I dislike Adam for the things he does on a football field ergo i boo him.
But hey now I'm painted as a racist and bigot for treating Adam like i treat any other person.
So let's not boo Adam so we don't let racists get away with it right. Unfortunately you have just segregated Adam out as being different and treated differently.
Segregation, treating people differently, forgive me i must be stupid but isn't that something Adam is striving to get rid of? Yet we have to do exactly that. The irony in this stance is ridiculous.
But some people are actually booing him for reasons that have been born out of racist attitudes, and as a result it's hard to differentiate which individuals are doing what and why, therefore by continuing to boo you're adding momentum to a larger group who at least for some people are being seen as behaving in a deliberately vilifying manner.
It's like the swastika, it was a symbol long before the Nazis started using it, but people learned to associate it with something negative. If you were doodling swastikas because you like the aesthetics of the symbol, you need to be aware of the larger context and that people may assume you are supporting the negative aspects that symbol represents.
I don't think Goodes should be be treated differently by saying you can't boo him, but the bigger problem is that he IS being treated differently by the crowds. This isn't comparable to anything else that has happened before. Not to this extent
