Do all religions indirectly attack each other?

There are many kind of religions, all with their own God/s and regulations. It seems that people from different religion never speak about their own Gods to other people, yet they’re taught and sure that their own God/ess is the real and right one.

I have been in to many preaching and religious speech where religious people are very blunt about their own belief and strongly belief that their own God/s is the only one for humanity but at the same time it seems like they’re ignorant, or never care about (probably on purpose) people from other religions out there, in the society. Many said that they respect other people’s Deities but does it mean they approve those other Gods?

Religious people of course, aware about the differences out there and in the way of realizing the truth about their own God/s but it really seems like they’re avoiding any controversy/contradiction with other religions out there. It’s evident that they only believe in their own teachings and Gods, and selfishly believe others are a group of rebellious people that worship the wrong God but why they elude any religious-arguments with people that worship different Gods than theirs? Are religious people just a bunch of coward people that assume this world the way they like and try to avoid any reality from it?
