No one on Sherdog is taking any guns away. If someone makes an argument, you should address the substance of the argument. If you also want to point out minor mistakes they made, like calling a magazine a clip, that's fine but don't focus on that to avoid the actual argument at hand. I see gun nuts do that frequently, often with the same minor mistake.
I call people who like guns gun nuts, take offensive if you'd like but none was intended. I hope you don't also find the term fan offensive just because its short for fanatic.
