Statements like this are less a message to those outside than indoctrination for those inside, a veneer to make dubs think they are actually tolerant of diversity. Very few people outside the organisation even know what JWs think less care about reading some statement online. The people who care about these things are inside and want to believe they are tolerant and the gap between their views and the rest of society is far less than it really is.
The reality is that when push comes to shove if you are gay then you will never be accepted unless you (a) suppress your sexuality and (b) be a Witness. It's the same as any so called tolerant Islamist believer claiming that all people are equal. There is no fence to sit on. If pushed on the subject then they have to accept that Muslims are OK and infidels are exactly that.
For Witnesses it is ultimately a black and white issue. Any veneer of tolerance peels away in seconds as soon as a person lives their life as they wish.
