Spot on with the informative list, Mr. Rankan! But I find myself surprised at one omission:
Women in pants, especially with short hair, and men in tight fitting pants or with colorful ties. It's a clear sign of being a dyke, wearing pants with short hair when women should leave their hair long as intended, and refrain from displaying their legs to men. Any woman displaying herself in such a way is trying to lead men into sinful fornication, or tempt the abominable ways of fellow gaydykes.
And no true godly, masculine man would wear tight fitting trousers, or a colorful tie, when they should be wearing something sober, possibly with a cross tie pin.
These are some of the surest indications of gayness in a co-worker, and people should be warned and made aware.
Keep up the good work, my devout friend!
