I dont think BCH itself is hated. I am pretty sure what everyone hates is the drama...
It is, just try posting something positive about Bitcoin Cash in /r/bitcoin, /r/cryptocurrency, Twitter, or other bot-heavy platforms. You'll get instant replies of "BCash [insult]"
As a miner and business operator, I got tired of the drama on the BTC side, with devs constantly advocating for restricting/reducing blocksize, changing algo, and similar retardation
