Hezbollah is the main political party in Lebanon. Anything can be related to the main political party of a country. It's like saying you can legally kill Israeli medics because they are "related to Likud".
In any case, killing medics is a violation of the Hague and Geneva conventions and the internal law.
If this story is hard for you to take seriously, there's thousands more stories, videos and witnessings of war crimes by Israel in very recent history..
This has always been and always will be an excuse for the person saying it to be a "violent, self-centered tribalist". Humans have worked together for the benefit of the community for the longest time. Rugged individualism is inherently linked to capitalism.
The previous comments were talking of IQ in a quantitative way ("x points less"), so they fit in the first definition.
Even the second definition is not really a thing. Intelligence as a concept doesn't mean much and needs to be defined properly. Using it this way is just another way to divide people superficially.
