You and Star Traveler’s contintion, may be correct in the klintoon sense of what the meaning of Is is.
If this ever comes to pass, the situation of being FORCED to rejoin (not readmitted), may not void the original intent and it damn sure won’t hinder any real Texans, if it ever comes to that. Just like the Texicans told the stinkin mexicans in 1836, COME AND TAKE IT, will certainly again apply to anyone wishing to interfere next time and with the same outcome.
Not to worry, it won’t come to pass. Far too many Texans are patriotic Americans. However, if you want to indulge your secessionist fantasies here on FR, feel free. Just don’t fool yourself into thinking that you’re doing anything other than indulging in mindless fantasy.
