Is BTC's huge hashrate a problem for BCH?

I've been away from BCH's developments for a while and I was wondering if the huge hashrate of BTC (or the low hashrate of BCH) is seen as a problem/risk by the community. For example, is it vulnerable right now to 51% attacks?

I'm not trying to flame. It's a legit doubt and I know that the best minds are in this community and that they are constantly thinking on how to improve BCH.
