As defined in Merriam Webster dictionary -
ethics : the discipline dealing with what is good and bad and with moral duty and obligation.
Honestly Swampman what is unethical about hunting with a semi automatic rifle? If you truly believe it then you are getting sucked into the Pelosi/Schumer/Biden/Kennedy black hole. That is a slippery slope you walk and it leads towards the absurd but very real bans as we have seen in the UK and Australia.
Oh - by the way, since Britain outlawed virtually all private ownership of firearms (by law or red tape) the crime rate with firearms has increased every year to over 300%.
I don't own an AR15.....yet .....but there is no problem with using it as a hunting tool. You obviously have had your logic and thinking molded by whatever the liberal media will have you believe......
It is clear by definition that "ethics" or the practice of have nothing to do with hunting with an AR. To not understand that would only indicate ignorance & the ability to grasp logic may be asking alot.
This explains why he cannot answer why it is unethical, he just can't.
