I completely agree. Modern scholarship is incredibly important for anyone who wants to take history seriously. Primary sources are paramount as well, but it is naive and cocky to the extreme for one to think that simply reading the primary sources will tell them all they need to know. Historians are trained to read primary sources critically and apply historiographical methods to come up with plausible conclusions about the past and to interpret sources and history. This is why modern scholarship is so valuable. The sort of people who dismiss all scholarship as 'propaganda' tend to be intellectually dishonest and in the pursuit of agendas that for probably good reason do not receive the support of modern scholarship.
