Yes i understand that Carol, but Islam is the subject at hand simply because Muslim terrorists are professing Islam, and committing atrocities in the name of 'allah'.

No it isn't. The reason Islam is being discussed in the way it is in this thread is because there are people (like you) who are trying to spread hatred towards all Muslims because of the actions of some Muslims.

There really are people who commit atrocities in the name of Christianity, Judaism, Hinduism, and many other religions... even today. But you don't tend to hear so much about them because the groups they belong to aren't the ones currently being scapegoated by the "powers that be".

For instance, it was Christians who committed the massacres at Sabra and Shatilla, and Jews who sent the heavily armed Christians into those undefended camps and left them alone while they did their dirty work.

whilst Islam remains centuries behind

Statements like this are misleading, not true, and also are designed to do one thing and one thing only... spread intolerance and hate.

You can't say "Islam is" anything at all since there are factions within Islam that have progressed just as far as the more liberal factions within any other religion. Making a blanket statement like that about Islam is simply a lie. It is not a lie to say that some factions within Islam remain centuries behind. But that can also be said about most other major religions.

Saying that Islam as a religion is centuries behind just because some factions within it may be centuries behind would be the same as if I said "White male Christians are rapists", just because some White male Christians are rapists.

Again, the problem is extremist fundamentalism. Not Islam itself.
