Hi Theland, I will answer your question, though the tone of the original post is somewhat flippant, your subsequent comments suggests you might be looking for sensible suggestions.
My opinion is that there is no difference in how a Christian, Atheist, Muslim, Jew, Buddhist, Rastafarian or any other group ‘should’ behave in order to meet the expectations of others.
Above all, be human and humane. See the good in people and events, rather than the bad. Behave toward others as you would want others to behave toward you.
There’s a mathematical basis for this, as well as the obvious moral stance and teachings of many sacred texts.
From a mathematical perspective, suppose that you can be a trouble-maker or a peace-maker. Thing is, there are other people in this world some of whom are trouble-makers, and some are peace-makers.
It is possible to prove, based on game theory, that the most successful strategy when interacting with others (in this model) has three elements.
You start off as a peace-maker and act cooperatively and play nice with everyone.
The second element is that when you come across a trouble-maker, you match their behaviour, engaging in arguments and generally be a bit of a pain in the a$s.
This strategy works up to a point, but the third element in the most successful strategy is, every now and then, act like a peace maker and play nice, even with the trouble makers. If they continue to be a$sholes, then you match their behaviour, until one day, you decide to play nice again – to give them a chance to show their peace-making, cooperative side.
Of course human interaction is vastly more complex than this, so such a simplistic strategy is far from a complete guide to human behaviour, but it’s a worthwhile start.
The crux of your question appears to be why do some get irritated when you Bear Witness about your God to others here.
The answer is contained above. Treat others as you would wish to be treated. Do you want someone from another faith community to repeatedly harangue you about their belief system and urge you to watch videos that are clearly (from your own perspective) full of misconceptions, lies and half-truths?
Maybe you would be comfortable with that, but I suspect, given your previous posts about different belief systems, that you would find it a bit irritating. You might get more irritated when, after you compare their views with your own, they don’t listen and continue to regurgitate their own view of reality at you, urging you to adopt their own belief system – a belief system that you ‘know’ is deeply flawed.
And when they do that repeatedly, you may find yourself regarding that person as being a bit ridiculous.
If you want respect, rather than ridicule, then find your cooperative, peace-making side.
Which is what you have been doing in recent weeks. That’s a good thing.
See: people notice. Keep it up :)
