Even in Saudi Arabia they don’t have footbaths in the airports. This is the same as the polio drops and the ham sandwich brouhaha. These scumbags are either preemptively appeasing (liberals) or reaching for power and influence way beyond the scope of what the average Muslim wants.(Islamofascists)
These extreme "rituals" as described in WMD aren't even followed by most muslims to this degree. The ones that do adhere to this stuff and demand these thingd through CAIR are the ones that blow people up, including other muslims, for not being muslim or not being muslim enough.
The reason liberals go along with these ideas?
Well, it's simple- when you're the loser you do whatever the victor demands, no matter how ridiculous.
