I'd say that is an ad hominem, or personal attack.

ad hominem:

A fallacy that attacks the person rather than dealing with the real issue in dispute.

when people can't find fault with an argument, they sometimes attack the arguer, substituting irrelevant assertions about that person's character for an analysis of the argument itself.

That's not practicing what you preach.

That also told me everything about you I need to know.

I understand that you see others doing it to you in some sort of fashion with the anti or liberal comment. However, it also tells me you are quick to abandon your standards, and lower yourself.

Your arguements state you stick to your beliefs, which is not evident by your actions (see above quote).

Add that in with the loss of a friend in a situation you lacked a holistic approach (because you were his friend) to,that caused you anguish... so much so I feel you may base your ideals on that. The change in beliefs (regarding age and weapon use)was probably a quick one, and one that came overnight when the accident occured. (Which is an assumption on my part, and would like to hear your response on it. My assumption although, seems based in logic per your words.)

Your belief systemappears to be built more on emotion than the tangible facts you've claimed (I would honestly like to review them, it is an important issue, I agree), but have failed to show.

I hasten to think what you would do if a loved one was clubbed to death with a ball bat...get rid of baseball as a sport?

I'm not attacking you, merely making assertions that seem to be relevant and backed up by your own word's in the arguement. I'm interested in finding out where you are coming from, honestly.

Now with that, I'd say the "muckrake" comment is an offense (personal attack) that constitutes a warning from the admin, or apology from you. If you are who you say you are, you'll offer up an apology (to the person you called a muckrake), and dispell my whole set of assertions by doing so.
