My opinion is simply in favor of the freedom (the right) to not have your property or person attacked. Is it just guns you have a problem with? What if Rittenhouse somehow managed to throat punch one of his attackers and killed them that way? Would that be more palatable to you?
I grew up around the influence of Systema and Krav Maga where the goal is mainly to overwhelm and obliterate an attacker by whatever means necessary. My main concern is who is in the right and who is in the wrong and have a hard time defending people who are in the wrong even if the consequences are extreme and disproportional to their offense, I do NOT feel this way after the fact when calmer heads can prevail and societal laws can assess
My positions on the unspeakable wrong deaths of Arbery, Floyd, and countless others should show that I at least try to be consistent and argue in good faith
