Didn't "miss" it, thank you. Simply ignored it, as an idiocy not worth even the minimal amount of "respect" necessary to swat it down like the poor, palsied thing it is/was.
Clearly, animals DO, in fact, "have rights" in this country. There are plainly worded, inviolable l-a-w-s against the most egregious forms of animal cruelty on the books in each and every state, in this country. That this (evidently) displeases you is -- I assure you -- of zero consequence whatsoever, in both the abstract and the particular.
Your "argument," such as it appears to be (it isn't presented coherently enough for one to be absolutely certain) is that said laws should not, in fact, exist, for some mumbled, street-crazy reason or another. That's as may (or may not) be; the fact remains, nonetheless, that said rights ARE a reality.
That short, yellow thing that whizzed by you, just now? The Clue Bus. Catch a ride.
