Eduard:
For a person of your depth of understanding of the English language I would think that you would be aware that most English words have multiple meanings. That is clearly true for the word "speculates" and its cognates. While I would not presume to teach you, for those who may be enamored with your fluency in language I will provide some accepted meanings that you have ignored:
1) To consider a subject or idea.
2) Contemplation of a profound nature.
3) Inference based on incomplete evidence.
In further consideration of the word "speculate" the implication is that there has been an orderly process of reasoning which has been based upon incomplete evidence. In view of this it can hardly be said that what I have said is " . . . close to 'unfounded, reckless, and completely removed from the facts assumptions.'" If anyone has an excited imagination over my post, it appears to be you. Oh, well, understanding that you very well may have to much time on your hands that is otherwise not put to useful purpose I can understand why my post might excite you. However, I would encourage you to sublimate your excitation if that is needed.
