Sarah, if you are a wuss it would surprise hell outta me! Speak with your instructor. Try a little harder to protect yourself. Refuse to train with the jerks who are more interested in hurting you than teaching you. If you MUST train with such morons, introduce THEM to some serious pain. While it is extremely important to be skilled enough to protect yourself, it is not cool to be seriously injured and / or lose work for a hobby. One must always evaluate the situation and act accordingly. I am sure that is exactly what you will do.
I see that anytime you post it attracts a lot of attention. Most of us enjoy your POV and find a woman who enjoys guy things refreshing and interesting. Hopefully you will ignore those few idiots who are not kind to you here. Most of us think AR15com is a better place because of you!
