Willful deceit and endangering your spouse is not a "lifestyle choice", it's wrong in an objective ethical sense.

Exposing your spouse to sexually transmitted diseases without their knowledge harms society as a whole. In cases where it's a wife cheating on a husband, forcing men to pay to raise children who are not their own harms society as a whole.

I'm not in favor of this kind of vigilantism either, by the way. But I think the relativism you express above, implying that cheating is a personal decision without a victim, is desperately in need of a reality check.

I admit that "lifestyle" is bad wording which sounds way too apologetic towards cheating. Of course there are victims, but society has still decided not to make cheating a punishable crime, nonetheless. My point is that it is not the duty of me to expose my fellow citizen, it is a private matter between that person and his/her spouse.
