If a Muslim dont go to temple or church it don't mean he is intolerant to Hinduism or Christianity. Tolerance is respecting the beliefs/opinions of others ..it don't mean accepting them
agreed tolerance is not going to worshipping others god, but tolerance is to understand that just like you believe your god is the one and only true god, others also do believe the same.
liberalism is tolerance towards rational criticism of your religion, and your religious text, practices etc.
liberalism is supporting the idea of secular state even if your religion is majority there.
liberalism is not to recognise everything in the name of religion.
for example : asking for Muslim candidate,asking for Muslim quotas in jobs,etc
liberalism is to understand that polygamy, underage marriage of girls, restriction on music and movies, restrictions womens dressing, etc is bad.
liberalism is to allow a cartoonists freedom to draw prophet muhammad's cartoon,ofcourse you can complain to the authorities about a derogatory cartoon, there are provisions in the law for that, but the derogatory, offensive etc is very subjective matter, it's a slippery slope, so let the court or sensor board decide the threshold, being ultra sensitive and saying I am offended makes no sense.
liberalism is to understand that something a state may need to prevent certain kind of dressing for security reasons. example -full face covering dress.
liberalism is to understand that for certain kind of jobs require certain kind of dressing and attire, if you are not comfortable with it try some other job which suits you.
liberalism is having a heart to sing a patriotic song.
liberalism is not to punish some one if he eat in public during the month of fasting.
