I have no problem with anyone taking a nuanced look through an entire piece while also considering the time and place when it was published. What I do have a problem with is cherry-picking through an hour plus of material and branding an entire work "problematic" or worse for a handful of jokes that were mainstream funny at the time and clearly jokes; the whole point of the profession. Most of this is amplified by social media and its ability to share short, out of context clips of anything but unfortunately there are real consequences that arise from that.
