The problem with white pride is that it is almost always organized in a hostile manner, attacking people of other ethnic backgrounds. If it were organized in a positive way, highlighting achievements, based on respect for mankind and providing for a system of in-group support rather than oppression of others, there would be nothing wrong with it. I suppose in most areas people might not see a need for it, but in say, Hawaii, where they used to have Kill Haole day and there is a strong and dominant Asian majority, it might be nice to have someone back you up.
Still, the existence of pride groups at all in America is a sign of failure and Balkanization (oh those lovely Balkans). America is no longer a salad bowl or a melting pot but a place where people come to scramble for the almighty dollar and fight for "what's theirs" at the expense of everyone else. Whites want to have "pride" because everyone else does, but the truth is that everyone, including whites, would rather whine about life being unfair than make things better for themselves and the country as a whole.
