This word which some western people hate it (especialy the Christians) , and they insulting/mock it all the time .
In my experience (history) in chat with non-muslims , some people refer it to Idol , and some others said to Allah mean the moon , some said it's mean "camel" ....etc
as you knw Arabic is semitic langauge , it's a sister with Aramaic and Hebrew ,
the Aramaic is the langauge of Jesus (pbuh) ,and Hebrew is language OT
In Aramaic Jesus (pbuh) called God "Elahi" , and Hebrew they called God "Eloah"
I don't blame the atheists if they insult Allah/God , because they don't believe in God/Allah any way .
what i blame here some christians , and some believers in God/Allah in other religions .
