I think you might be confusing posts and forum members a bit
but that is of no consequence. You have heard from many of us and we all agree that you will require the personal services of an IP attorney in your area if you are considering a lawsuit.
To emphasis the difficulty that we on the forum have in assessing whether a work is infringing or not, the following is from the US Supreme Court opinion in
Harper & Row: "It follows that infringement of copyright must be based on a taking of literary form, as opposed to the ideas or information contained in a copyrighted work. Deciding whether an infringing appropriation of form has occurred is difficult for at least two reasons. First, the distinction between literary form and information and ideas is often elusive in practice. Second, infringement must be based on a
substantial appropriation of literary form. This determination is equally challenging. Not surprisingly, the test for infringement has defied precise formulation. In general, though, the inquiry proceeds along two axes:
how closely has the second author tracked the first author's particular language and structure of presentation; and
how much of the first author's language and structure has the second author appropriated."
Copyright law sounds simple enough but there is generally nothing simple about determining whether one work infringes on the rights of another.
Good luck.
