I see people expressing their opinions much more openly and forcefully than on this board. I also see people questioning the 'troll' label being applied to all who disbelieve the abduction theory. I see people recommending that others read the PJ files. A lot of the posts could be reproduced on here without breaking the forum rules.
I think describing the tweets as 'vile' or spewing bile' is an exaggeration. The reason for the exaggeration is clear. Silencing their critics has been a large part of the McCann's defensive strategy from the start. It's very difficult to silence people on twitter so the strategy has been to demonise them.
That is an exact summation of the situation.
We see the same tactics employed on here as well.
There also seems to be several posters on here who are not prepared to accept that there are vile people among the Mccann supporters, and that is also a clear strategy, to be in DENIAL.
