OK that's a good attitude to have - educate yourself on the topic and consider your position further. As to the principle you were arguing from, it's unclear to me, but ypu may like to reflext on the fact that White people have been conquering, settling, civilising and building societies across the world for hundreds of years. It is known as Western Civilisation. You benefit from it directly, so your principle, as you referred to it, is at best hypocritical.
