Okay. I don't know off the top of my head.
The text from the site N gives is:
...«Мы должны ненавидеть: Ненависть это основа Коммунизма; Дети должны ненавидеть своих родителей, Если это так, то дети в наших руках», говорил Ленин, Записи Конгресса, том 77, стр. 1539-40.
«Мы ненавидим христианство и христиан. Даже лучшие среди них должны рассматриваться как наши худшие враги. Они проповедуют любовь к ближнему. Это противоположно нашим интересам. Что нам надо – это ненависть. Только тогда мы завоюем мир». Анатолий Луначарский...
The first bit is "'We must hate: hatred is a foundation of Communism; Children should hate their parents - if it is so, then children are in our hands' said Lenin, notes of the Congress, vol. 77 pp. 1539-40."
The second quote is from Anatoliy Lunacharsky, supposedly, but doesn't sound much like him: "'We hate Christianity and Christians. Even more so, between ourselves we must consider [them] as our worst enemies. They preach love to those nearest. This is the antithesis of our interests. What we need is hate. Only then will we conquer the world'. Anatoliy Lunacharsky [Jew]"
The whole document that it's taken from is titled "The USSR under the Jewish Yoke", however, and it's a series of 'quotes' which in their totality spell out anti-Semitic propaganda. Hardly a trustworthy source.
I suspect that some Communists might have said something similar. Because the destruction of the traditional family was quite high on the agenda of some, following on from the traditional position that the 'bourgeois family' was perpetuating old, bourgeois interests. You should note that the 'quote' from Lenin above is actually talking about plain alienation of children from parents, and not simply children being told to hate non-Communists.
In any case, even searching for the first four or five words of the Lenin 'quote' as given in the anti-Semitic tract above turns over no more results on a Russian search engine. I don't see the quote as particularly remarkable, although Lenin was generally pretty traditional when it came to the family, but I can't see any evidence yet, after just exploring the page N cited above (and saw himself as a fabrication), that Lenin did indeed say it or something similar.
