They've lost a lot with Portnoy leaving. He gave DT balls, and now their left with some sissy ballads with some sick riffs, and an excess of what sounds like 80s style synth. BLECH!
I hate to burst your bubble, but that's likely not a Boreal Chickadee. It's nape has too much white and it's cap is too black. It's much more likely to be a Black-capped Chickadee.
It's considered "offensive" because it displays a Confederate flag. Nothing more than censorship. Stupid stupid censorship.
