This is opinion, not citation. Here's what he said:

> White people are a rapidly diminishing minority of global population

Which unless you have any extra context, according to me does not entail:

> we need white solidarity to survive because non-white people are a threat to white men

Elon replied with 100 emoji to a post that said “If White men become a minority, we will be slaughtered. Remember, if non-Whites openly hate White men while White men hold a collective majority, then they will be 1000x times more hostile and cruel when they are a majority over Whites. White solidarity is the only way to survive.”
