What's good for the goose is good for the gander. The pro gay lobbies, such as GLAAD, are some of the biggest bullying associations on the planet, as seen with the Duck Dynasty dust up. They're all for Phil Robertson losing his job for speaking his beliefs, and I'm sure Kluwe is probably on board with that. Now he sees there are two sides to that coin.
When Phil Robertson backers were claiming his right to freedom of speech was being infringed upon, the anti-Phil faction was quick to point out it wasn't the government who was acting against him, so free speech didn't apply. They said Phil had the right to speak out, but there can be other ramifications, such as commercial and financial interests. Same thing here. Kluwe does have the right to speak out, but he better be ready to deal with the consequences.
