There were almost no atheists in Mohamed's day. Islam started on a path of military conquest with him. Islam has never been a "religion of peace". From the invasion of Spain onwards, Islam was an invasive religion always on the attack, in Spain, France, Italy, India, and elsewhere, all the way to the final attack on Vienna in 1683. Islam has been making attacks on peaceful nations that never attacked Islam in any way. The reason Islam stopped that was because Islamic nations became military weak and incapable of continuing on in that manner. Even in Bangladesh, Pakistan showed itself not a nation of peace when it killed 3 million people in what is now Bangladesh, and India had to militarily step in to stop the slaughter.
Now you're starting to stretch the historical evidence too far. The expansionism ebbed and flowed over the centuries - it was not some non-stop assault on anyone and everyone around all Muslim societies. And it's not that remarkable when compared to Christianity's track record of expansion, which is arguably a lot worse. It was driven overwhelmingly by self-interest and circumstance, like most expansionism. Far more complicated than simple religious bloodlust. And Islam spread in many places totally absent military invasion.
In Europe, Islam was an incessant problem for centuries.
Not the only one, we had vikings and Norsemen, but the history of Islam cannot be whitewashed in this fashion. Nor does the expansion of Spain in the New World et al excuse Islam.
