The problem with that situation is that Muhammad (pbuh) and even the caliphates that followed all ensured that those who are christians and jews that they would not be harmed and that their livelihood, worship, families, business etc... would be protected by the Muslims.
There is of course no caliphate today, and every moe and sam of the middle-east does what their village says.
The problem is lack of education on both sides. Non-muslims and even muslims who lack knowledge of Islam.
You can't become Muslims by forced submission of a human being as by very definition Islam is submission to no creation but to God almighty alone.
There's plenty of examples of poorly practicing Muslims who do things that are forbidden in islam. Be it alcohol, be it bribery, etc...
One of the poor impressions of Muslims while leaving Africa my family experienced was a guy not letting us on the plane to Canada and asking for a bribe. My father saw a woman with hijab nearby working and that was the lasting impression my family had of Muslims. Ironically today my mother wears hijab and my whole family became Muslim
Bribery is forbidden in islam btw but is very common in certain arab countries.
There is a lot of turmoil in arab countries at the moment as Muslims have been oppressed for decades by tyranical secular dictatorships. Unfortnuately do to meddling by western forces (political, military, etc...) certain christians groups were working in coercsion with the american and other western governments, as such there is a backlash against certain christian groups. Most unfortunate but it is a complicated political situation.
For instance as Christians at the time we would go to church, we were clearly not muslims by appearance or by common race but everything was good, in the last decade+ there has been more political turmoil instilled by the west and as such... amongst the ignorant but very upset and angry masses there is emotional whiplash.
And don't think for a second all the Christian arabs are all nice and sweet, I had tons of Arab Christian friends. Don't think for a second all of them are innocent and just a victim of select muslim anger/ignorance.
For instance just as there are clowns on here who promote hatred of islam there are arab christians who do the same. Just take as an example that recent 'film' which attacked Muhammad (pbuh) with various lies, homosexual porn, etc... They are viscous.
Unfortunately innoscent christians get backlash due to certain idiot's actions and cooperation with the west political death machine.
