Think it through for a moment: The International School of Ministry is a school that licenses ministers. The hypothetical customer who would do business with them is either looking to license ministers or become a licensed minister. You are now that hypothetical customer, you either want to license ministers or become licensed as a minister and you'd heard about an "ISOM" which may suit your needs. You go to Google, you type in ISOM, and you see this:
Option 1: International School of Ministry ISOM - "The world's largest Bible school..."
Option 2: Rippaverse - "Avery Silman was once an entry-level hero known as Isom..."
Option 3: ISOM Online - "...the internet's most affordable and effective institution... for the work of ministry."
Trademark law probably looks at these matters differently, but to the hypothetical person looking for ministry resources, this is not confusing whatsoever. Let's go further though, because another issue is whether they might construe these as being somehow related. That page returned in the results doesn't use the term "school" or "ministry" anywhere. It never mentions Christ, the cross, any spirituality or religion, and the controversial and "confusing Cross" on the belt? you have to scroll down to see it, and it's literally this:
My setup uses a 50 inch 4k monitor and I only spotted it because I'd heard so damn much about how this cross will make people think "ahhh, so this is that organization that licenses the ministers!" Most people are scrolling on their smartphones. If you hit the "page down" key 5 times, then you can also spot this one:
If they watch through the video at the top of the page, they'll get a brief glimpse of this "cross" at 1:30:
That's after 90 seconds of being told by a black man this is a Rippaverse comic book. If they make it another 90 seconds, they can get a better glimpse at the "cross":
You'd have to sit through three minutes of being told repeatedly that this is a comic book from a company named Rippaverse before you see this cross. That's three minutes of never mentioning Christ, ministry, religion, or anything related to the ISOM in California. Again, this is from the perspective of a hypothetical person who wants to license ministers or become a licensed minister. Nothing indicates this is even a religious invocation of the cross.
As for the NOW existing drama videos, those videos are centered around how these two separate and distinct entities are now entangled in a lawsuit... how the fuck would that make someone believe they're the same company? That's the dumbest argument yet. A video about them being different companies will make people think they're the same. Makes perfect sense.
EDIT: Forgot to point out that there are more images and depictions of Isom without the cross on that page than there are images of him with the cross.
