Welcome to knowing, most of us have been waiting on someone to take it all down for a very long time.
Can you imagine people used to say never discuss politics.
The people got conned into thinking this , this allows them to stew in ignorance. Mature people can discuss anything and they aren't supposed to cling to things they are not masters of.
If you can't defend a position that means you might be wrong or need more work, so tweak and try again and grow.
Imagine if we have always talked to each other in that way we would not be in this mess today.
