blunt beaks and stellar opposition

What compels the majority of Indian writers of English to abuse the word against in various blog posts, paid articles and various parochial portals? Does not the damage implied by the collision worry them? Do they fail to appreciate the use of opposite instead? How does one explain some random actress appearing against a superstar? Was it a game of tennis? Was it sumo wrestling? Was it a game of cards? Was it arm wrestling? Or was it squash? It seems to be none of these, for the "writers" (who really have no business wielding the pen in the language) choose this word to mean that said starlet was appearing along with said superstar. They're on the same team, on the same side. Talk about dushaasan appearing against duryodhan in the mahaabhaarat. It's time to rally against the opposition.
