First, you cite some bunk internet survey for your statistics--equals ZERO credibility.
Second, you have no concept of the various options presented a front-wiper, i.e., back to front and/or front to back. Utilization of BOTH procedures conclusively removes any chance that the taint will not be properly cared for.
Third, and most important, what you uppity back-wipers neglect to tell everyone is that after you reach around and wipe you (one in particular, based on his Spring Break testimony) then bring the soiled shit-ticket around and out of the porcelain--raise it to your FACE--and proceed to INSPECT it to determine the amount of hot feces still remaining in your slot.
Any competent front-wiper does not need to take such extreme measures. Shit-tickets go straight from the brown-eye to the bowl--no questions asked. End of story.
I recommend all of you back-wipers go to this website: firstname.lastname@example.org
Later taters. I'm out. I hate you all.
