Does anyone have a problem with Jehovah's witnesses?

so i have this friend and i have been his friend for upwards of 8 years. i consider him one of my closest friends. well he happens to be a jehovas witness. well anytime we start to talk about something, and his religion is brought up (which seems to be quite often here for a while) we get into a debate about it. his beleifs are so different from mine that they create alot of friction. i have no problem with being friends with him. and i have no problem with his religion. i just dont agree with it. well he pretty much told me that all religion exept for his is "the false religion" as described in the bible. (i am a baptist.) that really hurts my feelings. cause i dont think that about his. i just dont agree with it. how could JW be so arraogant to denounce all other religion ecpecially another christian one. your thoughts?
