"...Are you saying that the followers of a particular religion are 'the enemy'? A religion, as opposed to a political group, nation or fanatical subgroup?..."
Almost. Damned close. Getting there.
It's not hard to do, when you are dealing with a Political and Cultural and Legal and Militancy mechanism married to a particular set of Religious Dogma, unlike any other mainstream religion; one that is used time-and-again to radicalize and militarize and mobilize adherents worldwide when advancing The Faith or defending Co-Religionists or when stealthily penetrating other cultures until a tipping-point is reached (see: Europe).
I would invalidate the idea myself in a heartbeat, if Spirituality or Religion were the only aspect of this belief-system; however, given its high-profile, extant, and highly-operative worldly and secular aspects and behaviors, tucked-into its Religious aspects so closely so as to come close to defying identification, well, the idea takes on considerable traction.
Your mileage obviously varies, and that's fine - just don't be surprised when the majority of your countrymen see through the disguise and object strenuously to the worldly and secular aspects of the belief-system enjoying as much protection as the Spiritual.
Your countrymen are a little more intelligent and sophisticated and perceptive than you are giving them credit for, I fear.
"...And how are we to define the word '"alien'?..."
Any belief system that originates from outside the European-Christian framework of Europe, the Americas, and most of Oceania, that forms the basis for our laws and culture and philosophy and worship and society.
There are relatively harmless 'alien' belief-systems like Hinduism and Buddhism which do not seek to change their host society (The West) and which do not become obnoxious and insistent upon their my-way-or-the-highway viewpoint and which safely and happily integrate with Western secular society.
And then there is Islam, which is
also an 'alien' belief-system, which does
not meet those criteria, in the eyes of a great many.
"...I'd also re-ask for time marks on some samples of this here 'propaganda'. You know, specifics. TIA."
No. The simple act of pitching Islam to the community is, itself, an act of propagandizing, so feel free to pick any time(s), from the opening moments of the meeting to the closing moments, that you feel worthwhile. I won't be investing any more time in that myself.
