i agree.  know well who is your brother and who is your enemy. don't call everyone brother, don't get tricked with "bro" or such word to get into your vocabulary and to use it recklessly.   know that enemies will designate you as an enemy even if you did nothing wrong to them, just because of who you are.  and enemies, followers of muhammed will lie that they are your friend and brothers, and use other such taqiya against you.
