The Judaism topic IS the Judaism forum. It’s the ONLY ONE on FR dealing with Judaism.
Get a grip.
Having the word Judaism in the "topic" field no more makes it a Judaism ONLY thread than having "Mainline Protestant" makes it a Mainline Protestant only thread. Here is what those fields say on this thread:
TOPICS: Judaism; Mainline Protestant; Religion & Culture; Click to Add Topic
KEYWORDS: anniversary; christendom; christians; europeanchristians; lutherans; martinluther; reformation; Click to Add Keyword
If you want ONLY ONE on FR dealing with Judaism, then open a thread under a Judaism Caucus. If you don't understand this, send a private message to the Religion Moderator. I'm sure it can be explained to you so you won't remain confused.
