Yes, but men and women stay on opposite sides of the room.
In South Africa, like most countries aside from the USA and the UK, the Jewish communities are overwhelmingly Orthodox. Whether or not a person who attends an Orthodox Synagogue is Orthodox in his "non-synagogue activities" is purely up to the believer. So, some members of the Orthodox community may not actually be observant Jews and would appear like Reform Jews in the USA. However, they would not call themselves Orthodox, but Jews who happen to belong to an Orthodox synagogue. Actual Orthodox Jews in South Africa would be indistinguishable from Orthodox Jews in the USA.
Orthodox Jews are taught to do everything "by the book" and believe ALL Jews should do the same.
Same Reason anybody else smokes.
Lox is cured salmon but this is not specific to Orthodox Jews. Lox is the same regardless of its being kosher or not.
Orthodox Jewish teenagers eat the same things all Orthodox Jews eat; kosher foods of all different kinds.
Orthodox Jews don't allow men and women to dance with each other, but all other Jews do. (Orthodox, while separating based on gender, do dance, but only with people of the same gender.)
The answer completely depends on the Reform Jew you are talking about. Orthodox Jews follow all of the laws (no driving, cooking, etc) and some Reform Jews do the exact same thing.
Same-sex marriage is prohibited by Islam, Orthodox Jews (and some Conservative Jews) and most Christian denominations.
The overwhelming majority of Jews accept homosexuality and support same-sex marriage. In fact, all branches of Judaism, except the Orthodox minority, recognize same-sex marriage.
There is no such thing as a "reformed" Jew. It is called "reform Jew". Reform Jews celebrate passover as a commoration of the exodus of the ancestors of the Jews from Egypt and into freedom, which is the same meaning passover has to Conservative and Orthodox Jews.
Many of them suffer the same uncertainty and concern regarding your life.
A 2012 poll shows that 78% of American Jews support same-sex marriage, while 21% oppose it. It should be noted that Orthodox Judaism does not accept same-sex marriage or sexual relations.
