Is a muslim fair if he:
I'm not sure if there are any verses in quran or hadith which promotes those points.
Giving respect is a very subjective concept, younger people can disagree with older people if older people are doing something or saying something which is fundamentally wrong to humanity. Disagreeing is considered as not showing respect by most elders, which I feel is wrong. We can respect & still disagree.
Your other two points clearly seems showing partiality. Not sure it's acceptable in islam.
But please share references if you find anything which promotes any of those things in islam.
