Toi: We don’t say we love people who are anti-religious. For me, personally, if someone is anti-religious, I have issues with them. I try to still love them as a Jew, but it’s hard. I would not invite them to my home, etc.
If someone was born and raised in a not-so-religious environment, and is interested in growing, yes, I will support them. It’s extremely difficult to start keeping Shabbos. If someone never did it before, and is interested in growing so they will eventually keep Shabbos, then I will try and help them. I won’t tell them it’s ok to turn on the AC on Shabbos, but if they do, I won’t yell at them for it. Show them that it is beautiful, and they will eventually accept it all.
