Ok, bit per bit:
I live in Berlin-Germany, maybe it's different here, so here are my observations/
my perception...

"Only, if you can show me any statistic which proves that this is a gay people problem.."> It was/happened on CSD (Christopher Street Day)...!?
That's proof enough. Even though you are right, there are all kinds of freaks and bad things happen every day from all sexualities, but this time it happened because of CSD.

I stepped out of church a long time ago, no fan of religions either,
and i think you find less religious people in the big cities.
The oppression you talk about comes more from the hillybillies
on the country side.
Come to Berlin, you will see it's vice versa.

"I'm heterosexual but no one ever promoted homosexuality to me and told me to try it. This does not happen. I have never heard of homosexuals trying to impose their lifestyle onto heterosexuals. The only thing they impose is being respected."
-It does happen. A gay man try to "touch" me in the sauna of my gym.
He was lucky i trained for 2 hours and had 3 saunas already, that's why i only called the police... the case was closed, because of lack of public interest.
-Yesterday in the park i saw an Ueber Bike with an big rainbow ad.:
"Proud and Loud!" in german
-I am an heterosexual german-italian, trained with a ballhead...
You have gays in the park "looking" for sex dates, thinking every
ballhead is gay. I have to put my Jamaican Cap on and put on some
bombaclaat dancehall :) to be "respected"

"I think we could need a bunch of people who do not want children, that's actually pretty good for our ecosystem."
-True. Those same people than should stay away from wanting
to raise children. A child should be raised in the balance of female
and male, representing the universal model of Man,Woman and Child.

So, Yes, unfortunately, everything described above, calls
actually for a Straight Parade.

But there's more to it:
Did you know that 80% of the Pro7/Sat1 Media AG top staff is gay.
One of germans biggest TV/Entertainment Companies. A friend i went to school with, she told me about it, she is working there...
Did you know that the Thermo Paper from credit cards and supermarket receipts, got 5000 times the allowed amount of BPA, and BPA is full of
oestrogen. You prob. think this is conspiracy, no, it's good research..:
The little boys are "pushed" into a certain direction:
Look at a 10 year old (soy)boy, and a 10 year old girl, already gettin
female curves....
It's goes deeper than you think...
