On line is a hard way to get to know people. When we are face to face we see the wry smile when an insult is given in jest. We can see when someone is becoming agitated or heated and change the subject. It is sometimes hard to pick up the same cues when all we have is the black and white. We also don't know the struggles that others are facing that may make them short tempered or intolerant of a point of view that is different from theirs.
Do not worry too much everyone is on their own life journey and a person may go through many transitions as they acquire knowledge that may cause them to modify what they believe to be true. Whilst it may be tempting to try impose an idea on someone else, personal growth needs us to work for our own answers to listen to opinions yes but look at the evidence ourselves and form conclusions. Robust debate that challenges our ideas is helpful providing it doesn't tip over into bullying. I haven't read the posts that spawned this one but carry on your research don't be discouraged be open minded and be excited by the challenge.
Don't judge others too harshly I found that the posters that seemed the harshest in my early months were ultimately the ones that stopped me falling back into old patterns of thinking and made me ask valuable questions.
