Here's my opinion on this:
Simon implies that there is no discrimination because the mom tells Sophia to tell her classmate about pandas.
I can see a couple of things happening.
Suppose Sophia goes and tells her classmate about the pandas. Her classmate, being a kid, is like "cool! I want to pet pandas too! How?"
And Sophia goes, "Well, you have to follow Jehovah's rules. And Jehovah's rules say that no one who is practicing homosexuality can go into paradise."
"Girl is like, but my two mommy's are gay!"
Sophia says, "well, they can change and please Jehovah, and you can be in paradise with them petting pandas"!
girl says: "what happens if they don't change?"
Sophia: "well... (Hesitates)... The Bible says they will be destroyed at armageddon."
The classmate gets scared, has trauma thinking that her moms are going to be murdered by God.
Scenario 2:
Kid being raised by JW's sees this video. He knows that he likes boys, not girls. He feels horrible and prays and prays to Jehovah to make him like girls, but to no avail.
Whether discriminatory or not or homophobic or not... The fact is, this video can result in extreme harm, up to and including suicide.
On another note, the Spanish Wikipedia suggests that the word "homonegative" be used instead of "homophobic" because of the first response of lots of people being "it's not a phobia"!
Cofty, you likely get pissed off when people say "it's only a theory" regarding evolution.
Let's leave semantics aside and focus on the potential harm this video could cause.
I see many good reasons why the video should be denounced.
I agree with SBF, they could STFU about homosexuality.
