How dare democrats attack me for supporting McCain?

Generations, including me, in my family served our country. You people have no right to attack me when my family fought and died for you. I lost two brothers in a war that I believe in and many others in my family died for the right to speak our minds. But you use it in slander and attack me how dare you. You have a problem with my choice of presidential candidates then join the army and after you have served then you have the right to attack me.
