Not really, she's trying to use the existence of that conflict to say that people are bigoted for talking about a different conflict. I suspect Yemen only matters to some people when they can try to use it in attempts to shutdown other conversations.
What has been happening in Yemen during the war there has been terrible. A person would be entirely justified in starting a thread, raising awareness, etc. And it is entirely possible for people to care about that as well as about the Israel-Gaza conflict.
There are a number of factors why the Yemen conflict might not be getting the same level of publicity just now as the Israel-Gaza conflict.
Newness is a factor that's very relevant in news coverage. It's horrible to think, but as humans we get used to things pretty quickly. When Russia first invaded Ukraine (which is a very big deal!), it was all over the news, every broadcaster had a live page, updates and articles constantly appearing. Now, it often isn't in the headlines at all. Because news media want clicks and purchases, and people want novelty. The situation in Yemen started in 2014. While there are still articles published, it's no longer got the newness that draws people in and it's complicated by a decade of fighting, wrongs and ethical quandaries. In contrast, the Israel-Gaza conflict is still pretty new.
Technology and social media is another front in this battle in a way that it wasn't in Yemen in 2014. Both Israelis and Palestinians are often highly technologically literate, having grown up with the internet and social media - there are things that can be communicated online now that just weren't feasible 10 years ago. So, people around the world can now see the actions of soldiers, the struggles faced by people trying to stay alive, the bodies of the dead, in a way that just didn't happen 10 years ago.
