Did any of you think that the brotherly or sisterly love in Islam was a bit OTT at times?
For example, it's common in almost every society to shake someones hand when you meet them, but when I was a Muslim I felt obliged to shake my fellow Muslims hand almost all the time!
I remember in the canteen in college/uni a lot of my Muslim friends used to sit around one table and when anyone else joined them they first used to shake everyones hand at the table before they sat down. Lest you miss anyone out!
I remember I used to feel a bit silly shaking every single brothers hand before I sat down, and I used to wonder what the onlooking non-Muslims were thinking.
Also, I know it's supposed to be a very kind gesture to call someone your "brother", but Muslims do it so much that they've almost demoted the real definition of the word brother, ie your biological brother.
One time I was having a conversation with a Muslim and he introduced me to his "brother", and I said "Oh is that your brother"?... and he then said... "Yes he's my brother in Islam"... and I just thought... "Oh".

Furthermore, I also disagree with calling every Muslim female your "sister". The terminology begins to gets slightly disturbing when a Muslim brother looks for a nice "sister" to get married to...

Again, I know it's supposed to be a very nice gesture to call them your sister and the intention is supposed to be good, but I just don't agree with it.
Do you guys have any other examples or experiences?
