You don't mind, that's your choice. Why should traffic come to a stop for a funeral? Why should the guy in the car behind me, on his way to visit his dying father have to waste ten minutes to pay respect to some drug gang shooter who beat his wife and abandoned his kids at age 5? Why should the woman trying to get to Sick Kids to visit her hospitalized kid have to needlessly waste time so that some greedy miserly bastard can have all his lodge mates follow his stiff to the burial ground? What about the guy in the SUV beside me that knew he could make it home before he had to pee until he had the bad luck to be caught by a funeral procession for someone he doesn't know or have any feelings for - and pisses his pants.
I realize not all dead people are *****. But many live ones are not ***** and time is precious to them. The dead guy is dead. If the family and loved ones want to celebrate the person's life and reflect on their relationship, they can do so without inflicting additional traffic woes on thousands of people. None of whom know the deceased and should not be forced to pay respects to someone that may not deserve any.
Have your funeral at the funeral home or wherever else you choose. Don't have it on a public thoroughfare. There is no need and it's self-absorbed.
Theres a large amount of irony in your last point that I won't point out. As I said...the death of common decency.
