It's pretty much the same in the Seventh-day Adventist church. It's considered to be a violation of the commandment not to kill as well as the concept of destroying the temple of the Holy Spirit. :)
Don't forget the anti-caffeine Mormons.
Seriously, once we begin going down that ever-narrowing and winding road of making our own convictions into law of God for all, there really is no end.
The Pharisees perfected it into a religions system, by which they could justify rejecting Jesus as the Messiah.
And I was in a similar group who would do the same, since I know Jesus would not bow down to their 'holiness' rules.
It is a very pernicious and self-righteousness thing, that ends up looking any and everywhere for some sort of 'sin' to condemn, and concludes with spying on any and everyone found committing such 'infractions' against the rules.
Avoiding the appearance of evil no more had anything to do with testimony Christ before the world, but seriously became a mechanism of fear and control, lest any of us be 'found transgressing' some new carnal rule to obey.
I know what I speak of, because I was one of those ministerial spies, that reported to the leadership I was rising up in.
But, as Paul said, I did it ignorantly in unbelief. The unbelief was in not believing the Scriptures as written only, and not holding only to the true Head of the body: Jesus Christ.
