Kudos for fighting the fight on behalf of those who can't fight it for themselves yet. (and who shouldn't be fighting that fight to begin with!)
What you're seeing here is the stereotypical attitude, complete with all stereotypes. I see it from the positive, because without failure the pro-circ side presents the same arguments- I can even predict them.
Thank you for starting this thread, because that was an excellent opportunity to give 'accidental' surfers who might not have children yet, something to think about. Don't get upset, you're doing an amazing job, how many children you have saved you might find out later... If you only saved ONE CHILD, you lived your life with purpose- and that I mean.
Cheers! Thank you for your courage, no matter what the topic, sexual orientation or other discrimination that humans feel entitled to- I recognize certain names! Don't EVER give up, you're making a HUGE difference on this planet today!
