I think you are right. The worst "of them" are probally the worst because they hold a doctrine they cannot defend. The issue is not the doctrine (there are godly people in both camps) but the way indoctrinated people hold views they do not understand (they are sometimes disciples not of Christ but of other men, and will defend their "cult" with unwavering and blind loyalty).You need to remember there was an entire thread started excusing that kind posting and blaming the recipients as feeling guilty as to why they were offended by it. Now in response to your questioning that antagonism they are guilty of the:
"tu quoque"
You avoided having to engage with criticism by turning it back on the accuser - you answered criticism with criticism.
Pronounced too-kwo-kwee. Literally translating as 'you too' this fallacy is also known as the appeal to hypocrisy. It is commonly employed as an effective red herring because it takes the heat off someone having to defend their argument, and instead shifts the focus back on to the person making the criticism.
Your logical fallacy is tu quoque
Lacking understanding all they can do is lash out. In return they deserve our prayers that God will open their hearts to the gospel of Christ rather than hostility in return. I run out of patience too quickly. We need the support of other Christians (not an affirmation of doctrine as there are differences in understanding but encouragement to respond in a Christ-like manner) when we deal with these types.
