I'd imagine there are also more murders overall as a result of domestic violence. Pointing out something is worse is not a defense for something that is bad. Boeing can't defend its airplane doors falling off with "but what about xyz car company's failing airbags!?" Yes, cars should be safe too, but that doesn't solve airplane's doors falling off mid-flight, does it? People can work to improve the safety of both.
In recent years we've had white supremacists shoot up synagogues, Jewish nursing homes, black churches, target Sikhs and Latinos, etc. It's a problem. It appears many right-wingers are such snowflakes, so ultra-sensitive to criticism, they'd rather let it continue unabated rather than reflect on its existence.
When the El Paso shooting happened in 2019 or 2020, the shooter wrote a literal manifesto and posted it online, talking about the great replacement theory and explaining he was motivated by the Christchurch mosque shooting in New Zealand. Multiple posters were just "nah, terror attacks from white nationalists aren't real. What about BLM and who they killed?"
