I think so one follows the Buddha’s teachings because we have examples it is the way to be genuinly at peace because it leads to freedom of suffering. No need to mingle with other methods/religions on ones path.
But the Buddha’s teachings are not leading to construct new walls, Buddha-walls, away from "others". For me the Buddha’s teachings are making clear there are no walls at all.
Tilopa: "Go beyond all spiritual methods."
Since Dzogchen is beyond religion, it is not rejecting nor accepting any thing
. H H Dalai Lama gave many teachings by showing the lack of these walls by respect in the variety of temples and churches.
Guru Nanak is very respected, he don’t pursue out of his mind to observe “others” but observes his mind itself. I guess in what then can be discovered are no walls but freedom.
Oh my illusive-self ! let me be with me.
Mr. cloud of nothing! you can command.
Even if I want to love ,you turn its hue to hate.
Originator of vices! you do not satisfy & stop.
Oh my bag of memories! leave me alone.
Mr. shade ghostly ! you are heavy on me.
Even If I want peace , you change it to agitation.
Producer of sensory mirage! you work during sleep as well.
Oh personality label ! you keep everybody different.
Mr. dis-ease ! you rear children of miasma.
Even if I want health, you reshape the malady.
Monitor of society ! you have robbed every body's sleep.
Oh lunatic ! just sit & let sit others.
Mr. prince terror! just remember death.
Destroyer of masses! you are cause underlying.
Even If somebody wants to get away, you try to hang him.
Oh non-being created by real Being ! ,

Oh non-entity ! let the real entity (Love) prevail for good.
Namaste and have a good day!
‘View like the sky’ means that nothing is held onto in any way whatsoever. You are not stuck anywhere at all. In other words, there is no discrimination as to what to accept and what to reject; no line is drawn separating one thing from another. ‘Conduct as fine as barley flour’ means that there is good and evil, and one needs to differentiate between the two. Give up negative deeds; practice the Dharma. In your behaviour, in your conduct, it is necessary to accept and reject.” Guru Rinpoche
