It should be noted that you're fighting a strawman. The OP was criticizing the religion islam, not muslims as a group, and certainly not making the claim that "all muslims are intolerant". To clarify, this doesn't mean other religions are particularly "good" either - it is possible for many things to be bad simultaneously.
To address your strawman however, I will note that the problems with islam run very deep. The fact is that a majority of muslims, globally, hold views that I would consider, amongst other things, to be misogynistic (feel free to update me on that if there is a more recent global study with the same scope).
If something is the norm in a group rather than a fringe idea, it can hardly be considered extremism either. Given that islam has many of these misogynistic values close to its' core, it isn't particularly shocking either and not too far fetched to attribute a share of the blame to the religion, regressive as it is.
As such, considering the above, I consider islam to be bad on the whole. Note: this doesn't mean that someone is inherently "bad" due to being muslim, or that "good" muslims don't exist - I am acquainted with a few.
