I disagree with the characterization of those described by the g0y site. But it's complicated.
First, the totality of that profile is too specific. There are men who reject anal. There are men who reject effeminate behavior. There are men who reject assumed black diva personas with the ghetto lingo. There are men who espouse philosophic virtue of equality in the partners. But all of these isms do not necessarily converge. If they do for the g0y faithful, then it will be a very few indeed.
What is true is that the oft promoted and sometimes adopted stereotype of Western gay men has been a problem to a great number of men. They obviously felt like the trope depicted in media and in some gay social circles was not representative of them. As time progresses and we find less opposition to out gays in Western societies, we will continue to see the erosion of the effeminate gay as the defining example in media. It already is displace in urban cultures, but remains in the broader population, especially among straight average Joe's who have no gay friends and little knowledge of the diversity of gay populations.
It's too egocentric to dismiss the dissenters as self-hating. And it's disrespectful. There are plenty of men whose chief sexual activity is not anal sex, but oral or other. There are plenty of men who don't enjoy being feminized, and it's not fear, it's self-perception. There are plenty of men who reject the notion of tops or bottoms as defining limits in sexual congress.
What we should be busy about in our time is the promotion of the spectrum of gay identities being represented, which includes those like g0y who may not even be respectful of that same diversity. It is important for the world to see and get to know the diversity of men who are gay. If you're tempted to remain part of the silent majority of gay men, remember that your silence is a big factor in the straight world's misperception of our numbers and our true composition, as diverse as theirs.
