But yes, you certainly can talk about your misguided views! And people can call out your misguided views as well!
All because of the 1A which is protected from outside forces with the strength of the US military.
Soldiers have little to do with policies such as the endless Middle East wars.

It's not the soldiers choosing proxy wars in Ukraine or the Middle East, it's congress.
I think you calling someone a war criminal is way outside of what is legitimate on this forum.
