Hassidic Jews (as opposed to the broader class of Orthodox Jews) tend to wear black coats and pants and white shirts, and Hassidic men usually grow full beards and wear hats at all times. As a result, from a distance, they look similar. (I have a Hassidic friend who sometimes shops in an Amish general store, he enjoys the confusion.) If you look closer, there are some differences that those on the inside notice immediately. Hassidic Jews generally have a mustache and beard, while the Amish generally shave their mustache. Hassidic men usually have tzitzit (strings) hanging out over their pants from their undershirt (also called a tzitzit or tallit-katan).
Another similarity is that both Hassidic Jews and Amish do not generally use Birth Control (aside from extended breast feeding, which does delay ovulation), and the result is very large families.
Note that Hassidic women and Amish women are harder to confuse. Both dress modestly, but Hassidic women usually wear wigs or headscarves, while Amish women usually wear a doily on their head when not wearing a bonnet. Both are covering their hair in response to the same biblical commandment. Also, Hassidic women tend to wear brighter colors.
Because Mormons, Orthodox Jews, and Amish have religious health codes forbidding drug use.
Hasidic Jews are a subcategory of Orthodox Jews. The majority of Hassidim wear long coats, while most other Orthodox Jews wear regular suits. On Sabbath and festivals, Hassidim wear a fur hat called a streimel, while other Orthodox Jews wear hats more similar to standard styles.
No, Amish and Jews are not the same. The Amish are a Christian sect and have no ties to Judaism at all. Until somewhat recently, in fact, the Amish were strong supersessionists meaning that they believed that Christianity replaced Judaism and that Judaism was no longer a valid path to G-d. The Amish are a sub-sect of the Mennonite Church (Annabaptist) and they are mainly of Swiss-German ancestry. The movement descends from the 16th century fellowship known as the Swiss Brethren. The languages that the Amish speak are Pennsylvania German, Swiss German, and English. They do not speak Yiddish, although, as Yiddish is largely made up of high German, most Yiddish speakers and Amish can communicate with each other quite easily. There are some Amish who claim Jewish ancestry. This is most likely the result of a 'conversos' scenario where Jews would claim to have converted to Christianity publicly but would practice Judaism in private to avoid persecution. As has been seen with other conversos groups, a percentage of the future generations lose all knowledge of Judaism and completely join Christianity. There are some similarities in practices between the Amish and Chassidic Jews in that both groups are very orthodox in their respective religious teachings, men from both groups can be mistaken for each other because of clothing choices, and both groups tend to have very large families. However, no Jewish sect rejects new technology in the way that the Amish do.
No.
Yes, non-Orthodox Jews can become Orthodox by becoming more observant. Non-Jews can become Orthodox Jews through Orthodox conversion.
Orthodox Jews are strictly observant. Hassidic Jews are even more strict.
Orthodox and Ultra-Orthodox Jews are strict followers of Jewish law.
Of course, Hassidic Jews emphasize the fact that they raise their children as Hassidic Jews, but in reality, there is significant intergenerational flow, with some children of Hassidic Jews departing for other streams of Judaism, and with some children of Liberal Jews joining more Orthodox streams. This seems typically human. There is a similar intergenerational flow between Christian denominations.
Unfortunately, in Israel, only Orthodox Jews get all the special privileges.
They are Jews who keep the Torah.
Haredi Jews are ultra orthodox Jews found around the world.
Orthodox Jews or Torah Jews.
