Kraut's biggest problems are his low IQ and his spitefulness, similar to Ethan. The difference is that Ralph gets salty and throws jabs on his show, whereas Kraut goes into turbo sperg mode and starts an online crusade, surrounding himself with dozens of cretins that help him do "research" for his internet pissing contests.
I don't give two shiny shits about Kraut's success as a YouTuber and I'm not in the business of advising restraint to autistic Germans on the internet, so if he goes after Ethan he should have a fighting chance. We know for a fact after the Lord Akira saga that Ralph is really insecure about his material well-being - an insecurity that's only rivaled by his manlet complex and his graying hair.
To those concern trolling about Kraut's channel - even if he starts making videos about Ethan, he won't be negatively affected. Wherever this could potentially lead - it can't possibly be worse than the gayops discord servers, and he bounced straight back from that. An example of a retard losing an internet beef is Sargon, who was more or less unaffected. The vast majority of their viewers only watch the videos they're interested in and don't care about this shit.
