I really don't think these things are games.... people are dogmatic about certain things , but that doesn't make it a game, the things people feel they need to do, that are both harmless to themselves or others, and they are not trying to force others to do it, and they are not standing in judgement of others who do, or do not (as the case may be) then it comes down to one thing, and one thing only, its between them and the Almighty.
Everyone who is in a relationship with our beloved Savior, should walk out their faith in the way they are being led to do so by Him, and if that looks different then what others are doing, or have been taught to do, then to put your self in the way and seek to "guide" them on the path we think they should be on, this is dangerous ground, this walk we are in is Spiritual and none of this is a game, those who daily take up their cross and follow Him do so in a walk of faith, there are souls in grievous bondage, others who are die never having experienced the love of God through His people, , we as followers of the Savior need to stand for truth and be prepared to treat others with the same patience and kindness by which He draws and leads us.
