OK boys, back on topic -and away from Nakura
DogpilingWhile this can be an issue, I think it comes under the "be respectful" blanket. I don't see a problem with five or six people debating one if they raise separate points of debate from each other and do it in a respectful manner. If it just happens to be a "Me-too" scenario, then that's something the mods can deal with as a respect issue. I don't see an issue that needs explicit mention. Again, the rules are designed for maximum flexibility in moderation while defining a few boundaries, and this is such a case-by-case issue that it isn't appropriately dealt with in any other way.
StereotypingSince this is basically what StarSlayer's suggestion is getting at, let's call it what it is. Again, this is covered under be respectful - it's inappropriate to disparage an entire group of HLP users based on what one person says, and this comes back to debate the issue, not the individual. I lean against including yet another tip to deal with something that's a respect issue and is a case-by-case matter.
Perceived double standardsThe important word is the first one - perceived.
The guidelines, as drafted, are designed to protect
who and what a person is - essential characteristics that are traits, not choices.
Religion is a choice. Anyone here has the right to choose whatever beliefs and religion they want to follow (or not); similarly, anyone else has the right to question/debate those choices because they are choices and not pre-determined. So, while some religious members of the board and some of various political slants may feel picked on, ultimately they have one of two choices:
1. Engage in respectful debate - the forum guidelines embrace most of the principles of free speech, so you always have the option of MORE speech, so long as it is respectful.
2. Disengage and ignore the discussion entirely.
Among those is not "3. Report the thread because waaa waaa someone on the Internet disagrees with my views/choices and I have the right not to have anyone else discuss them." No. You have the right to be treated and debated respectfully as an individual, you have the right to refuse to debate, and you have the right to hold whatever beliefs you wish. Your beliefs do not have the right to be free from debate or scrutiny, whatever they may be.
In short, the rules cover this - if someone is being disrespectful to someone else, we have moderation for that. If someone is disparaging a belief set and not an individual, they are free to do that. The way the guidelines are written, you are protected from offensive personal remarks or attacks. The same is not true of a belief you hold. Examples:
Not OK: Battuta, you're an overly-analytical scientifically-bigoted bastard and should be shot into a black hole.
OK: Battuta, I have to disagree with the science behind your views, and frankly I think the science responsible for the theory of gravity should be shot into a supposed black hole.
Not OK: Goober, you're a conservative Christian asshole who deserves to be smacked.
OK: Those Conservatives and Christians who belief homosexuals deserve unequal treatment before the law are collective assholes who should be smacked.
Not OK: MP-Ryan, you're a liberal commie-loving douchebag.
OK: Liberals are practically Communists, and history shows that a lot of Communists are douchebags.
I think this quite adequately demonstrates the difference between an attack on a person, and an attack on a series of beliefs. You'll also note that there is no shortage of ways to debate these attacks on beliefs and make it abundantly clear that anyone making those sorts of generalized attacks is being pretty facile/foolish in their methods, and counteract those points entirely.
In short: I don't think changes are required. People are free from disrespect toward their person; they are not free from being offended because someone disagrees with beliefs they happen to hold. Any attempt to reverse that smacks of anti-blasphemy laws, wherein people seem to think they have the right not to be offended by someone else who isn't disrespecting them individually. The "double standard" is one where people confuse criticism of traits with criticism of choices; the first rightfully is protected, the latter rightfully is not.
