There is one problem
while your motive is ok, your way to go about it is flawed
they love to use senerio us or hypotheticals like you do
what if...
they use the same sins you used, immorality, sexual sin, etc.
their hypotheticals are flawed. Because it does not account for the fact that ever sin in Gods eyes has the penalty of death, and in reality, they are no better than the sinners they are judging, the fact they have not come to this conclusion just proves they have not yet fully repented, they still think they have some good in them, or they would never judge certain people (onlyGod can judge)
in what you did, you supported them, and basically gave them more ammunition. Because you made the same mistake they did. Using a hypothetical that does not support your cause. .
