Can someone explain to me why a religion made by a pedophile-barbarian is somehow tolerated and even defended against "islamophobia" (is e.g. a gay guy phobic for being scared of muslims that given power would throw him from a building or persecute him in some other way at least)?

Their whole ideology (as it basically governs every aspect of life) is crude, vile, barbaric and dangerous. The animosity towards them is well grounded, anyone saying otherwise should read their "holy" scriptures and just analyze how they behave when having majority (muslim countries)
