Salaam all,
If there's no alcohol content - and never will be any alcohol content - then it's not a haraam drink. I don't personally like the taste (ginger, yuk!), but there's nothing wrong with it at all.
As for the word beer, then it's just a word...Did Allah forbid us from using certain words?! Using the mere word 'beer' does not make one impolite, rude, or unislamic. It is not a swearword. It just refers to the style of the drink, which just so happens to be more commonly associated with the alcoholic kind. In some contexts, the word "sex" can be haraam, but if we are referring to legitimate sex within a male-female married couple, does that make sex itself haraam? No.
There is no need for confusion amongst Muslims who follow Quran and Sunnah...We already have access to knowledge about what is right and what is wrong, and seeing someone drinking a beverage labelled with the word 'beer' should not confuse us, as we know that ginger beer does not have any alcohol! Sometimes we read too much into things, when we should just stick to the God-given facts and words!
As for imitating the kuffar, I'm not sure about that...once again, the drink does not contain alcohol, or any other forbidden substances. It is drinking alcohol itself that would make us imitators of the kuffar in this instance, which we are not.
Think of all the kuffar (and even polytheists, in India and the likes) that drink tea!! This does not make tea haraam
A guy I know used to drink non-alcoholic beer (not ginger beer...real beer, minus the ethanol), because he really liked the taste...at the same time, he was a practising Muslim - a very good one too.
Anyway, I hope you are all well...I have been away from this forum for a while :-D
