Sorry, maybe you're rusty on measurement.  There is no agreed upon measure or method of crowd size for marches in DC.  None is in place. 

Each marching group seems to generate their own numbers, or various press outlets (of different leanings) decides to generate their own!    No standard, no agreed upon modulus.

The best way to measure such events is through - believe it or not - portajohn volumes.  It just happens to be a good proxy measure for crowds, a proxy of some sort, but it does tend to bear up.  

But your point is similar to the problem of each Catholic getting to decide the criteria for moral behavior.  Babble and worse (e.g., abortion is argued by some to be moral behavior).   So you've added unwittingly to the argument that the Church needs to be the provider and interpreter of the moral law. Tks. 

So you've self revealed the problem with the Catholic left, quite by accident, of course.
