No, that wouldn't be a straw man argument. If you're going to try to call fallacy on something you would have to argue appeal to hypocrisy. However the hypocrisy is based on your post and previous posts calling for a boycott for something you find morally reprehensible while at the same time using a platform created by the morally reprehensible. One you have a problem with the other you do not. It calls into question your own morals when they only serve you when you think they should. That's all.
