for that other anon here you go

i'm not very religious and was raised more culturally. non-religious jewishness is still just as valid, and i personally don't believe patrilineal jews have to convert (unless you really want to or want to convert to orthodoxy). i've been pretty disconnected from my city's jewish community but that doesn't make me any less jewish. same goes for you

yeah a lot of people have pointed out examples of antisemitism in the series. i've never read harry potter but i know some issues are the goblins (idk if that's what they're called but the ones who run the banks); jewish coding of some other characters; and the fact that there is one, count em one, jewish character that JK rowling passed off as "jewish representation" or whatever.but like i said i am not a fan of the series and know nothing about it other than what i hear from others.

they are still jews. while you may not identify as religiously jewish, you are still ethnically/culturally jewish. there's a lot of jews who identify as one or the other (or both).

yes they are absolutely jewish. i only have a jewish dad and while many people have tried to deny my jewishness, they cannot change the fact i was raised jewish and followed the religion my whole life. don't let anyone try to convince you otherwise with "halakhically jewish" narishkayt either

historically jews couldn't work other jobs and had to take jobs as money lenders or bankers. this is basically where the stereotype comes from.

hatred of jews goes back literally 2,000 years starting with the death of jesus. christianity was originally a sect of judaism, but theological differences over recognizing jesus as the messiah split them into two distinct religions. the death of jesus was blamed on the jews and so begins the saga of antisemitism. because antisemitism has been going on for so long in all parts of the world, it would be really hard to give a concise history of antisemitism. i would recommend reading "antisemitism: a western tradition" which explains the history of antisemitism throughout europe. there's also other books and resources on the history of antisemitism and quite a few of them are available as free pdf's.

in my opinion it is okay to attend synagogue services as long as you are being completely respectful about it and follow the rules of the synagogue (ex. dressing modestly, wearing a kippah, etc). most synagogues also have celebrations for holidays; for instance my local temple has a purim party every year with fun activities, and if you're in the know you can attend that. but of course if you wish to participate in holiday festivals you should do research and understand the significance on them. but i really do not recommend getting involved with more solemn/deeply religious holidays like yom kippur or yom ha'shoah.

there are many jewish mexicans. perhaps she feels hurt because mexico is such a catholic country and if that is your heritage and tradition, she may feel you are abandoning that. however, anyone is allowed to convert to judaism, as long as they are genuine about it. if you still want to convert, being open with your mom and having a meaningful discussion may make it easier (if you have that kind of relationship with your mom).

check my recent post about conversion and jewish genealogy; someone asked a similar question. good luck!

it's not overreacting. if they keep doing it tell a teacher or principal. hate speech is not protected under the constitution within a school setting. students only have free speech if their actions do not disrupt learning or harm other students. saying "heil hitler" and nazi saluting is definitely a violation.
