If you think being gay is wrong which I do then don't feel guilty one bit. Lgbt will try to put a guilt trip on you because thats how cults work. All you can do is tell your sister that what she is doing you think is wrong and its normal to think that.
Its like if your sister was a drug addict. You can tell her doing drugs are wrong. Its not hate its actually love.
Tell her that you will be a brother to her but her girlfriend will not be part of your life, its not hate no matter how many lgbt say it is. No guilt. And there is a reason why your sister rejects a normal relationship.
Was she abused or have no self esteem or went through a divorce? SheRicardo why is it that pedophiles to little children? When did they make that choice?
Needs to not reject the very lifestyle that brought her into this world. And don't let lgbt make you believe that its not christian yo reject your sisters lifestyle. Jesus may have talked with sinners but he didn't accpet doing wrong as normal or right.
If you were a pedophile would your sister accept you if you told her you were born that way even if you didn't touch one child.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
