" A discussion which constantly complains about comparative amounts spent on dogs/ cats/students/the homeless is puerile."

I wonder how many homeless people would regard the above as puerile?
To ponder the merits of placing annimal housing over and above that of humans? The fact that such a discussion exists displays magnificently man's inhumanity to man.
Does that come under the heading of puerile? I rather think not!
Your rant would appear to make the case that life is not fair. At least you understand something!
