When what I said then contradicts what I say nowIt's not uncommon to see some people who state something which is objectionable to some other people and when they are criticised they say that they did not mean what they said that way and that it was others who twisted their statement. What they meant was this and that and so on. This is common nowadays and we are almost accustomed to listening to such contradictory statements, which ensues to debunking by the same person who uttered the statement. And we also have become either naive or innocent or brainwashed or indifferent that we forget what, actually, they uttered and what was the effect or how their statement could bring havoc in the long run.
This tendency or practice is more common in politics. You hear a controversial statement of a politician and when the statement is criticised by people, he begins to belie his own statement and gives clarification and surprisingly, some people bow their heart before the new statement and they forget what his original statement was.
