B"H amazing, the Rabbi Kremzy on behalf of Yitzchok Nissim in Montreal kicks out a Jew from eating and hanging out in a shul, because he says this makes people uncomfortable, and the rabbi goes unchecked - except for a woman who doesn't even fully keep the Shabat, and as she is wearing, or not wearing the proper attire, she spots the Rabbi with his wife and son, she puts on her shoes and in a polite and respectful manner, she admonishes him for 15 minutes!
In the 3 weeks between the 17th of Tamuz and the 10th of Av the Jews mourn the destruction of the Temples, the main cause of the destruction was the baseless hatred that existed in their camps. Nowadays many people try to impose their views on other people and when they are rejected they say what about loving a fellow Jew.... So I don't really like conjuring up this value, but recently I have seen a number of times Jews getting kicked out of shuls, I never in my life saw anything like this (except of course from the zionist state which I've seen many times forcibly remove holy Jews from the western wall - a very terrible site - but that is what we expect from the zionist state, but from simple synagogues in the exile???).
