Person A: "I really don't think weed should be illegal."
Person B: "Oh yeah, so what about raping rural villagers to death? I guess you think that should be legal too huh?"
This is how ridiculous you sound.

The line is here: in a private communication between people anything can be said, nothing should be censored. if someone gets caught planning or doing something illegal they go to jail.
