There may be an increase in off the cuff rudeness to people you are unlikely to meet, as the internet makes that so much easier with fewer immediate consequences, but (at least here in the UK) we do not have anywhere near the same level of serious personal attacks. You might be more likely to encounter someone on the internet who is willing to be rude to you for your opinion, but you are much less likely to meet someone on the street that is willing to beat you up for it.
