Response: You have confused yourself. In post 23, you ended the post stating for me t back my claim that islam spread defensively and to remove oppression. That is why in response, I referred to the crusades as an example, as it shows that the Byzantine empire started the crusades. The Romans have very much to do with the issue, because it is you who suggested that the muslims attacked first when in actuality, the muslims were responding in defense from the Romans and Persians, who were aiding tribes to defeat the muslims. An examole is the battle of Tikrit.
Again you are confusing yourself and the issue. In post 23 I guess you missed the four links I posted in direct reference to the sieges of Constantinople. I guess you also missed that this conversation started with my question about the sieges of Constantinople fitting your ideas about islams expansion. I specifically made the question very narrow so you would not wander as it turns out you did anyways. As far as the Romans and Persians go once you can find some kind of justification that if either of those two attack it is okay to then go and attack the byzantines you might be onto something but until that time you are simply muddying the waters. You mention this battle of Tikrit which in your previous post you named Tikrik, you can't get the name correct and you can't find any proof of your claims until you do this claim is less than nothing.
And since it is clear that your are limited to resources, then you should desist in claiming your evidence to be correct. For I can name countless of resources in which your computer search may not find. This, and the fact that you can not prove your sources are accurate, discredits you from claiming you have proven your point. The best for you to do is be a skeptic. There's nothing wrong in being a skeptic and pin pointing all that you see to be an error, even in my logic or resources, or questioning logic to find the truth. I have no problem with your sources. Use whatever you fill necessary. What I'm questioning is your logic if how you concluded your sources as true.
You have never named any of your resources or provided anything even close to proof of what you have said. If you can name countless resources lets see some of them. I have asked you if you don't like the source I used then name the source you want me to use and I will use it, instead you give me this.
Btw, you can google the battle of Tikrik in 637 A.D. to get information. However, I do not claim that all of what you'll find will be accurate, but just some info on the issue. What you find that may be valid for your stance or questionable can be brought forward for further discussion and an open-mind to the truth.
You can't even keep the name straight in the same post and I did Google the name you gave and came up with nothing but references to Tikrit. If you found a reference to it please provide a link. Why is it you don't think you have to give proof of your claims but do nothing but complain when others do in fact provide backing for their claims.
