Why do ex jws and secular people in this group get mad that jws shun?

It states in the Bible at 1 Corinthians 5:13 “Remove the wicked man from among yourselves”.

It’s not the governing body that made this rule. If you believe that the Bible is literally Gods love letter to us then you believe everything the Bible says is true. So why do you not understand the reason jw shun disfellowshipped ones? Also so you know they’re actually not automatically shunned. It’s only if the individual continues to act in a manner where they committ serious sin and DO NOT REPENT of their sin do they get shunned. I find it humorous that you guys expect jws to deny Gods literal words and instructions on how to deal with people who make it blatantly obvious they no longer even want to be apart of the organization. Should they just shrug and keep allowing the unrepentant sinner to stick around the group and corrupt them? Yes I said corrupt because serious sin usually involves sexual sin, drugs, alcoholic etc etc the list goes on. And also disfellowshipped ones are still technically allowed to attend meetings and any other activities jw conduct. In fact they can always come back and repent of their sin; the sin that offends God as he wrote in the Bible not to commit. If they repent they are no longer disfellowshipped. I don’t get what y’all really don’t understand about shunning. Technically in other religions especially Muslims if you disobey Allah or go against what is written in the Koran you get more than shunned, you get killed as an act of honor….
