The term "ram down one's throat" refers to aggressively forcing someone to accept or believe something. There are several alternative expressions that can be used to convey a similar meaning. For instance, "force-feed" implies a similar sense of compulsion, as does the phrase "cram down one's throat." You can also use "stuff down one's throat" or "shove down one's throat." A slightly softer alternative is "push onto someone," which implies a level of pressure without the extremity of "ram down one's throat." Ultimately, the choice of replacement terminology will depend on the level of emphasis one wishes to impart to the situation.
