In the meantime,

Engaging a BNP supporter online in a chat forum may not affect their opinion, but anyone reading the thread will be able to read through the debate and if they are undecided they will be swayed by the more persuasive argument.

Don't forget that there are many people who read these threads without posting, some of whom are just passing through and not even regular mudcat lurkers.

Anyone reading through the above thread would see that the BNP has been thoroughly discredited and the BNP supporter has been able to provide no defence of his position.

In that regard, the above thread is serving an extremely useful and effective purpose.

Those posts which contain little substance will be given little if any attention and the more substantive and patiently explained posts will have the most influence.
