The problem is not just on message boards but also in person too. People are sometimes disrespectful to each other because they become emotional and passionate about the topic.
However, we’re not very persuasive when overheated. We just sound like a pushover. The best way for people to get their point across is to Talk Calmly. Takes discipline but is more effective.
While sometimes people need advice, there are many who are fine and following halacha. We might not agree with them, but we can still try to get along.
What we should do is not look at the outside but the inside and see the specialness that’s in every Jew
What concerns me is how the BT feels. They come so inspired by Judaism and then find people arguing etc. We need to be a GOOD EXAMPLE for them and help them continue being inspired. Example is a much stronger teacher than words. When people see people acting nicely, enjoying Shabbos, being tznius, they’re inspired to also.
