There is (1) Basic Principle of Morality:

"Love works no ill towards a neighbor"
- is the foundational principle for all common law.

Any mindset to violate that principle is defined as: immoral.

Glaring Conclusion: Since the vast majority of Sexually Transmitted Diseases among people involve anal vectors; -- Plus the gamut of research that clearly shows numerous complications of both physical & psychological nature in regard to people who participate in the fetish; -- The practice of anal penetration as a sexual fetish violates the Basic Principle above, & is therefore: immoral.

Corollary: People who promote practices that are destructive (immoral), - are themselves: immoral persons (appealing to fraud & callous disregard as their fundamental philosophy of self governance). 

Being a guy who luvs guys is not a choice - nor does love lend itself to ill; But willfully engaging in anal-sex fetishes, is a choice, -- one most dangerous.

If the shoe fits wear it.  If not, don't force it...

G0YS: More than just a name:

Despite the flood of e-mails affirming that this website has hit the mark with many men, there are some critics (mostly of the BPT genre), who question the fact that G0YS are different from gAy. Despite the fact that the feedback makes the point clearly, we want to take this space & stress that G0YS are as different from gAys, as wheat is from tares (weeds), Furthermore, most G0YS have a deep seated belief that there will come a day where the (2) are distinguished for the acts performed in their tenure among men.  The wheat will be gathered & stored, but the tares will be bundled & burned. So, in the most literal sense of the terms: Despite the fact that they indeed love men, G0YS are N0T 'Fags'.

Does MORALITY Matter?

Since you'll be dead much longer than you'll be alive, a very important question arises:
Which side of the line matters more?

Actually ... that's a trick question.  Everybody believes the infinity side matters more.
The difference is that one philosophy will take steps to prepare for it responsibly; -- While others will pretend it is of no consequence...

What do you suppose the cost of being wrong is?
