There are a few elements present in this question. I think that the first issue is that it is really difficult to attempt to link a modern experience to the Holocaust. Part of what makes the Holocaust so painful and so brutal is that the connections forged to it have to be in a specific political context and situation. It seems inconceivable that students in a modern classroom experience on a daily basis what was endured and suffered through the Holocaust. If the question is posed to individuals who are subject to practices of ethnic cleansing or autocratic abuses of power through subjugation, then there could be some connection. This being said, there might be some level of link when the Holocaust is examined as a violation of trust or an act of political or social silence. If this is the case, then the question might be best to be amended to cover this aspect.
This might all be put aside on the issue of "relation." If the issue of "relation" is one where individuals are able to forge connection to some aspect of the Holocaust, then this particular question becomes highly subjective, one based on the experience of individuals and the answers provided will be individualistic and personal.
