I don't think charging sales taxes on internet purchases is a bad thing. You should pay sales taxes based on where you live.
Otherwise an internet merchant has an unfair advantage over the local businesses that not only collect sales taxes, but also pay property taxes, income taxes, and corporate taxes in the communities they serve.
When you talk about "internet taxes" you should be talking about taxing dot com owners a "property tax" on the value of their domains or adding a VAT tax to anything sold online....those would be bad things that would hurt ecommerce.
Shopping online shouldn't be taxed in and of itself, however it shouldn't be a way to avoid paying taxes altogether.
