No. You were probably thinking about "cultural assimilation," which, although not "forced," occurs without requiring the consent of the assimilated.
The word "assimilate," standing alone, is not restricted to culture, which is a narrower use of the word, but rather, much more broadly, suggests the willing adoption of a thing, whether it be, as given in the second first definition provided infra, information, ideas, or culture.
1. to take in and incorporate as one's own; absorb (dictionary.com)
1. take in (information, ideas, or culture) and understand fully. (oxforddictionaries.com)
So, you see, you apparently use the word "assimilate" as a homo habilis would use a club, bluntly and broadly thrashing about, with only one understood application, that being to bash.
I, on the other hand, used the word "assimilate" in a refined manner, like a brush used by a painter, suggesting an image of chipivaug slowly, forcibly converting others to his madcap posting style, irrespective of culture.
