How would BCH be immune to any possible problems with USDT when the USDT/BCH trading pair on binance is the biggest one on the market ?

The 2nd biggest trading pair for BCH is again a USDT/BCH pair. The 6th and 7th largest trading pairs are with USDT as well. (https://coinmarketcap.com/currencies/bitcoin-cash/markets/).
I see a lot of people saying how tether just pumps up the price of BTC and when tether implodes it's going to take out BTC with it. Why is that not the case for BCH ? Is it because more of the global volume of the BTC/usdt pair is around 8 or 9% versus BCH's 1%. Still if tether takes out BTC it's gonna do some serious damage to BCH, no ?
