Am I wrong about this? Personally, I think that videos and comments that don't use any profanity or off-color words will be received better by the voting populace.

There are ways to strongly emphasize points without using profanity. And there is a whole segment of our population that will be turned off by the use of profanity. In addition, and in general, the people who generally use profanity who watch videos that have no profanity in them, respect this, and are more apt to accept such videos.

While this particular video is not all that bad in the profanity and off-color areas, it would be even better without it.
