I think it's that you just pasted up the link to the book without going into any detail whatsoever.Calm your passions I hereby advise - crucially, not advertise - cannabis.
My most humble and effusive apologies for posting about an alternate history book involving Operation Sealion on an alternate history website called alternatehistory.com in a thread dedicated to Operation Sealion. I will NEVER, I repeat, NEVER do that again.
If you'd gone into detail about HOW you think a Sealion could have taken place (précis level, a few thousand words) and then said you covered it in more detail in a book... then it's perhaps a little more grey. But as is, your post consisted in entirety of "Buy my book!"
Also, your entire postings on this forum consisted of three other posts and an advert.
