Evil needs to be exterminated, wherever it is found.
When was the last time you saw a rainbow... now just what promise does that refer to.
The problem is that we ALL have evil. The policy you want would come back on you. Islam is, perhaps, just more honest about it.
Or to put it even better, evil will exterminate you unless you meet it in God’s way.
The devil is hoping you will answer Islam in an Islamic manner, just with religion changed.
The extermination of evil is not accomplished by attacking it with evil. The fallacy of SJW and Islam is the same. Both seek to attack evil with a greater evil. In so doing they become the source of evil while that which they attack is most commonly innocent.
