Chofetz chaim says to bring Mashiach need to love everyone.

Huh?

Source?

The way to bring Moshiach, is for Moshiach to come to Israel immediately. After Israel, Moshiach will go to the top of Mount Sinai. It can happen right now and if not right now then it must happen tomorrow.

The beginning of the Geulah will start on the 16th of September if Klal Yisroel lets it happen. And Klal Yisroel can and will make it happen!

Yes. All Jews who are keeping torah and mitzvahs must love each other. There us no obligation to love open sinners.

I see that the concept of Ahavas Yisroel is still having a hard time finding its place here, after all of these years .

Ivory: Where is your source? The forefather of the Moshiach, Dovid Hamelech, transgressed both privately and befarhesiyah. He was called out, and he did teshuva. Were his subjects and those who came after not obliged to love him? We all transgress. Sometimes we do it because we think its right or justified, sometimes we are ashamed of it. But each one of us does it, openly and not. You would have us hate each other and ourselves. That is a miserable existence. I can’t presume like so many do, to know what hashem wants of us. But he didn’t create us for misery.

somejewiknow: How do you know someone hates hashem, unless they actually say “I hate hashem?” The truth is you don’t know. And let’s say they did make that statement. Even then, the Truth is, you still don’t know. You don’t know anything about them, you don’t know anything about their losses, or challenges, or upbringing, You don’t know the balance sheet they may have full of Mitzvos and sacrifice. You don’t know what tzaar might have brought them to that statement – speak to a survivor of the Shoah, and you might begin to get a clue. Actually, you may know nothing at all, except the certainty of your own kedusha. As for loving reshayim; We say in the Hagodoh every single year that the rosho is at his father’s seder table. His father might be justly angered by his son, but he loves him enough to have him at his seder. Who are you to define loving the rosho (who is your brother, or neighbor, or fellow Jew) as sinas chinom? And even in the CC quoted by ujm, he didn’t advise one to hate the kofer or apikorus, rather, in the specific circumstances described, to mock their kefira.

In a time of such danger for the Jewish people, and with such a revealed need for achdus, maybe, just maybe, you might consider letting the Dayon HoEmes be the one to judge Jews, rather than arrogating that responsibility for yourself.

At the end of Shmiras HaLashon (Hilchos Rechilus 9:15), the Chofetz Chaim writes that the prohibitions against Lashon Hara and Rechilus do not apply to reshaim and kofrim and that it is, in fact, a mitzvah to mock such persons

UJM,

I would be very careful to research when and with whom these halachos apply.

Eliyahu Hanovi and Yeshayohu Hanovi were punished for speaking disparagingly about Jewish IDOL WORSHIPERS (the real kind) – because “אין הקב”ה רוצה במי שאומר דילטורייא על ישראל”.
(שהש”ר פ”א, ו (א). רש”י ישעי’ ו, ו. ועוד)

The Rambam writes that if such great tzaddikim were punished, how much more so a קל מקלי העולם who dares to condemn so many Yidden as פושעים ורשעים וגויים ופסולי עדות וכופרים בה’ אלהי ישראל.
(אגרת השמד פ”ב)

I would err on the side of speaking positively about Jews.
