Is it bigoted to denounce Islam as immoral and even 'disgusting'?

[zasterguava]

Sorry if this is the wrong forum, but I'm pretty shook up right now. Earlier, in a heated debate I caused a woman to run out the room screaming I was a 'bigot' for saying Islam (I also mentioned Catholicism) is inately evil and its preachings disgusting and immoral- and before her going crazy saying I 'hate' Islam (not Muslims).

I am willing to reconsider my stance or atleast reconsider if I should use my freedom of speech [very limited in UK concerning religion] openly if the general consensus is I am a bigot- based on my extensive research on Islam I have a moral obligation to oppose Islam as I do any religion. If she'd called me Satan atleast I wouldnot have been so tongue-tied:

"But here steps in Satan, the eternal rebel, the first free-thinker and emancipator of worlds. He makes man ashamed of his bestial ignorance and obedience; he emancipates him, stamps upon his brow the seal of liberty and humanity, in urging him to disobey and eat of the fruit of knowledge."
