Logically it doesn't make sense to kick people who buy the helmet, people are frustrated by the illogical decisions by people. They abuse the fact that if you can get a few people to start a vote kick in LFR that person is usually gone regardless of what they are doing. By the logic of people in this thread, it makes more sense to kick the quiet top dps/healer who does their job and doesn't stand in anything wrong than to kick the troll in raid or the guy pulling 30k dps.
By the logic being displayed in this thread because people bought the helmet with their own money, they need to have rocks thrown at them. I understand people hate the shop but let people buy what they want and instead continue opposing the store on the forums. What do you really accomplish by kicking someone in an LFR with the helmet? Another will come, and another and another. They will still get their raid done one way or the other and the most you are doing is forcing Blizzard to make an alternative to the kicking system that is being abused.
Again for the drones who will read what they want, I posted on MMO champ and the WoW US forums that the helmets should be purchasable in game as well for around 100k gold per helmet. It allows people to use in-game currency to also buy the helmet, hell make it 200k even. It becomes another gold sink and it allows every player of WoW to get the helmet. However even though I do strongly believe that is how the store should be, allowing people to either pay IRL or use in-game currency for COSMETIC items I will not punish anyone buying them. I will take my concerns up with Blizzard and simply not drop the issue, if that doesn't work then don't buy the helmet. Personally I find my challenge mode helmet to be superior to the helmets and other warlock helmets to be better. You aren't solving the problem by kicking people, you are only taking a already rude community and making it worse. This seems to be more emotionally driven that "I hate this so anyone who buys it deserves to be punished!".
It also doesn't help that a lot of the anti-shop people look down upon the others and the way they use their words it indicates that they believe themselves to be higher. What do you expect from the pro-shop people? To just take your sarcasm and smile?
The logic is lacking here. I trust you don't play any sort of video games then since paying for them just means you pay to watch and move pixels right? You pay Blizzard so that you can watch certain pixels move a certain way by your logic. Blizzard has added a lot of mini pets to the store, how come those people weren't kicked from LFRs and shunned? Shouldn't Lil'Rag drop from Ragnaros and Lil'KT from Kel'thuzad? Why are mounts in the PET store? Why not kick them? Why is it that this whole discussion and fuse happens when a COSMETIC PIECE OF ARMOR is added to the game?
Pets and Mounts affect ACHIEVEMENT POINTS and yet barely anyone is lifting an eye brow. A cosmetic helmet doesn't improve your gameplay or affect your achievement points but it is suddenly the huge focal point of many WoW players? Am I missing something here? If I am please tell me what I am missing in a logical explanation and maybe I can see things from your perspective.
