Ask one of Jehovah's Witnesses

[Tonus]

Are you suggesting that homosexuals can get baptised as JW as long as they're not practicing?

Keep in mind that for JWs (as for many Christian denominations) homosexuality is not a thing that people are, it's a thing that they choose or it is a condition they are afflicted with.  Therefore, the term for them typically refers to the act and not the person or 'condition.'  After all, the Bible doesn't refer to homosexuals, but to the act of gay sex.  As far as Yahweh is concerned, homosexuality describes an act and not a person.  In that context, the term "practicing homosexual" is no different from "homosexual."

I think that the progress that western society has made in accepting homosexuality has forced religion to deal with the issue in different terms.  I think that the original view would have been that there is no such thing as a homosexual person, just people who have gay sex because they're perverts and degenerates.  Religion is being forced to address the reality that some people have a natural attraction to the same sex, and that having gay sex is not deviant behavior for them-- heterosexual sex is.  So it's not unusual to see the term homosexuality become muddled in a conversation like this.

JWs do not recognize homosexual unions/marriage, and a gay person who is sexually active is a fornicator and therefore ineligible to become a baptized member of the organization.  Considering that such action by a baptized member would likely result in being disfellowshipped, it's better to refuse to allow a baptism under those circumstances, which would effectively entrap the person.  However, a person who is not a fornicator (gay or hetero) is free to be baptized as he/she is showing devotion and loyalty to god by abstaining from sinful practices.

Regarding the acceptable minimum age for baptism, there isn't one.  A person is expected to understand scripture and be old enough to understand the commitment he or she is making when joining the organization as a baptized member.  For most people raised in the faith, this won't happen until their mid-to-late teens (I was 17 when I was baptized, having wanted to do so since I was around 14 and made to wait by my mother) and sometimes even later.  But I have heard of baptisms of people as young as nine and eleven, when they were announced at conventions or in literature.  It is disturbing to see such young people promoted as good examples, as it might pressure parents into pushing their own children into early baptism.  Baptism for the JWs is a kind of contract between the individual and the organization, and the penalties for rejecting the organization can be very harsh if a person's family and friends are baptized JWs.  To have a non-adult enter into such an arrangement strikes me as a very bad idea.
