Would everyone love it? But like the image shown it can be a shaky concept, easily manipulated and used for some other cause. Throughout history, we've seen empires fall and rise, but has any of these powers solely lived of ideologies based on peace and love? Is it actually possible to sustain it without heavily arming ourselves and creating a worse police state than what Europe has become? Do not mistake "peace and love" for multiculturalism, because it isn't as such, merely it rejects all forms opposite of it. I believe it could work and be very much used against what has become of the west. As for how it'd be implemented, I'd say it'd be very hard to make people accept this. There are two reasons to this; rejection and sustainability.
But that is not to say that it's impossible there still exists a way to go about it. It could be used for against the "protection of cultures & ideologies which are against our beliefs & our cultures", perhaps it oughta be possible to reinstate this banner for our cause? Think about it the mass would easily love it, although they'd be wary of it still is a far better concept than any other form as of late, and could easily be used as a means to push for a better society, which emphasises our beliefs, not the other side. Which is inferior.
